More WriteAttr -> WriteAttrString cleanup across the tree.

Some of these were correct as they were ... but most weren't.
There are a variety of other correct ones I didn't change over yet
that someone else probably should (GCI task?).

Keymap: Add ability to remove a key mapping

... of a normal (non-modifier) key via a right click menu.

Some more code style corrections of Keymap.

Keymap: Add Defaults button to revert keymap

Fixes #9980

Since hrev44455 we save your modifier keys settings when you switch
keymaps so you could get your modifiers keys messed up and unable to
get back to normal. This Defaults button allows you to override all
that and go back to the default US-International keymap with default
modifiers so you can start with a fresh slate and set things up the
way you want.

Also moved Revert button to the left side next to the Defaults button.
We do this on other preflets, the right side is reserved for an Apply
or OK button, and, if the preflet doesn't have one, is left empty.

Cut off the trailing spaces from the key dump.

* Noticed these on the keymap changes made by John, however, I have no
idea how they did get there (the keymap command doesn't use this code).

Preserve state of lock keys when keymap is loaded.

Keymap changes from recent activity. No AltGr yet.

Below is a mostly complete summary of the changes in this commit.

* Set the DeadKeys for the US-International Keymap to use the Option map.
* Rename American keymap to US
* Update the US, US-International, and United-Kingdom keymaps to take
out unneeded spaces in the option layer. Also updated the dead keys
and some other keys on the US-International keyboard to use UTF-8
characters rather than there ASCII equivalents when different.
* Make the Option key fall-through when there is no mapping in the Option
table. Option is for special characters, if none, print the regular one.
This is mostly meant for the US keymap which has an empty option map. But
also so that you don't have to repeat the normal, shift, and caps maps in
the option map needlessly. Although the keymaps are still not empty in
some cases that it could be like numpad keys and space.
* Update the /bin/keymap app to use fputs() instead of printf() when there
is no actual formatting taking place. I've gotten into trouble for doing
this before and it is faster to not process the string unnecessarily.
* Also several 80-char limit style fixes and updated comments.
* In Keymap class Reorder the modifier keys to match the keymap files.
Put B_CONTROL_KEY check above B_OPTION_KEY. Neither change has any effect,
they are purely aesthetic.
* Update DumpKeymap() method to use the abbreviated modifier letters so it
will fit in your 80-char wide terminal.
* Tiny style fix in InputServer
* 80-char limit style fix in BWindow and add a comment that the shortcut
gets eaten in the case of Cmd+Q
* Implement IndexForModifier() in KeyboardLayout, although I am not using it.
* Take Caps Lock out of the Modifier keys window because I couldn't get
it to work the way I wanted it to.
* Move key roles to the left column, and the key label on the left. Add column
header labels. Thanks Rimas!
* Add validation and improve marking menu options. Add a 'Disabled' option
to control, option, and command menus to disable the key. Make the key
role text grey if the key roles is disabled. Validation ensures that you
cannot repeat the same key twice in the Modifier keys window since that
won't work. You can't define 2 sets of option keys even if you really want
to. You can disable your control, option, and command keys if you
want, but that is not recommended.
* Rename kUpdateModifiers to kUpdateModifierKeys message to differetiate
it from kUpdateModifier.
* Add shift key to Modifier keys window, use the stop icon instead of the
warning icon to indicate conflicts.
* Allow the Layout system to control the size of the Modifier keys window
again, set the width's of the key role lables to the widest, set the width
of the menu fields to take up the rest of the space minus room for the
conflict views. I didn't like it that the Modifier keys window would change
size based on what options you had selected in the menu fields. Now it
doesn't, but, the layout system still makes it all fit.

* Added missing 'const' for the entry_ref paramter of Load(), and Save().
* Cleaned up Keymap.h.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41331 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Factored out a single base class out of the three Keymap implementations we
had in our tree.
* Adapted Keymap, <input>keyboard, and consoled to use it - the additional
functionality is implemented via a subclass in the first two cases.
* "keymap" will come next.

* removed KeymapMessageFilter, as it is no longer needed
* fixed a couple of issues with respect to internal/external naming of
keymaps and the respective files, hopefully such that there's always one
keymap active in the view: either one that has been selected or (Current)
if any changes have been applied
* replaced the dead-key-menubar with a menufield (thanks Axel, looking much
better)
cleanup:
* removed remnants of Use-button (message constant and switch-case)
* dropped 'Save' menu item, as it wasn't implemented anyway and would now
never be enabled
* removed fFirstTime, as it caused problems, but did not serve any purpose
anymore


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30734 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30721 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added support for selecting the dead key trigger characters from a menubar,
offering two choices for acute and diaeresis as well as allowing to switch
off each dead key completely.
* moved the textview on a line of its own such that the dead key menu and
the modifier-switching button live together on one line
* added enum dead_key_index and used it at a couple of places instead of
having to use the magic numbers 1-5
* refactored the actual updating of the fChars buffer from SetKey() into
_SetChars(), which is now being invoked by SetDeadKeyTrigger(), too

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30718 a95241bf-73f2-0310-859d-f6bbb57e9c96

* dead keys can now be enabled/disabled via middle mouse button
* fDragKey must be reset in MouseUp() as otherwise it is not possible to
drag a key from one keymap to the textview and then from the textview to the
same key of another keymap
* _HandleDeadKey() now ignores modifier keys as otherwise dead keys that
required pressing a modifier (like the tilde on the German keyboard) failed
to highlight the resulting characters
What's still missing is a way to edit the resulting characters for each dead key, but I am not yet sure how to do that in an elegant way

keyboard input server add-on. We should really have a common source for this
somewhere...

BControlLook plus some clipping to do its magic).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29703 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The message filter now does not do anything anymore when the source keymap
matches his own (field now added to the KeyboardLayoutView fake B_KEY_DOWN
messages).
* The default action for keyboard to keyboard drag&drop is to switch the keys
now.
* When a key is overwritten by a drop, the old key is now sent to the text
view, so that it's not lost (if that was a mistake you can now easily revert
it without having to press the "Revert" button and lose all changes).
* Cleanup.
