WebPositive: Dropdown menu for choosing search engine

- Move the list of search engines used for search shortcuts to
SettingsKeys.cpp/h and remove need for dynamic allocation.
- Use it in the settings window to help filling the default search
engine field.

WebPositive Add option to start new session on startup

* Add settings file entry "start up policy", with two options:
resume prior session, and start new session

* Add dropdown to settings window to select option (defaulting
to "resume prior session", which is the behaviour prior to
this patch)

* Add code to check setting on launch and open a new session,
or reload the prior session as specified.

* The "Start new session" option behaves in the same manner as
opening a new window, following the user's already specified
new window option

* Related comment 2 of bug #14890

WebPositive: Add support to show/hide bookmark bar

Default is shown, a menu option in the View menu allows you to show
or hide the bar.

Also move the bookmark bar below the tab frame, it looks better
here I think and matches other browsers (e.g. Firefox.)

WebPositive: Removed wrong license text from all files ...

... which were technically never distributed by Apple nor
are derived from code distributed by Apple. Only BrowserApp
and BrowserWindow were originally derived from code that used
to be part of WebKit and was distributed by Apple.

Removed executable flag. No functional changes.

Add optional username/password fields to Web+ proxy settings.

Add a setting to show or hide the Home button. I find it pretty useless myself.

While I was able to add this fairly easily by cutting and pasting, it was still
quite a bit of work. Seems like there should be a less-verbose way of doing
this. But it did work the first time I tested, so I can't complain too much.

* Moved auto-hiding the mouse pointer into BWebView::Pulse().
* Unhide the interface when the user invokes CMD-L (Open location).
* Make sure the progress bar is really hidden, sometimes it would be
visible again after unhiding the rest of the interface.
* Added a setting for the auto-hiding the mouse pointer feature. It defaults
to true, since I think it's useful for an app where the pointer would
usually be in the way.
* Hide the mouse pointer in any case as soon as the user begins typing, also
hide potentially showing tool tips in that case.

* Moved "Auto-hide" menu item into Settings window, as a check box along the
"show tabs if single page only" option.
* Fixed problems with showing tabs when opening new tabs while the interface
was hidden. Introduced a new flag which tracks the hidden state to make
this easier.

Implemented an "auto-hide the interface" feature for the full-screen mode. The
mouse cursor will automatically hide if you don't move it, unless it's over the
interface. The interface will disappear after three seconds if the cursor is
not above it. It will re-appear when you touch the top of the screen with the
mouse. I find this the best solution, since the mouse is also used for
navigation in the page, and showing the interface based on some virtual area
of the interface would just get in the way.

* Added page for proxy server configuration to the Settings window.
* Added necessary wiring in BWebSettings for proxy server configuration.

Actual proxy server usage untested, feedback welcome.

* Improved the layout of the Settings window general page.
* Allow specifying a start and a search page in the Settings window.
* Separated the "New page" policy into "New window" and "New tab" policies.
For a new window, the user can chose to "Open start page", "Open search page"
and "Open blank page". The default changed to "Open start page" and the
default start page points to the "Welcome" readme. For new tabs, there is
an additional choice "Clone current page". The default stayed with opening
a blank page.
* Implemented the new page policies in BrowserWindow.
* Listen for changes of the new settings in BrowserWindow.
* Added the new settings keys and default values to SettingsKeys.

* Moved some settings keys into new files SettingsKeys.h/cpp to make it less
likely to introduce erros with spelling settings keys wrong somewhere.
* Introduced new setting for the behavior if tabs should show at all if only
one page is showing in a window. Defaults to on, i.e. the previous behavior.
