DeskCalc: fix live updating of button text color

When using the panel background color, always use the matching panel
text color from system preferences.

When using a custom color, compute appropriate light or dark text color
to go with it.

DeskCalc: fix translation of key labels

The labels were never actually translated, only marked for use in
catalogs. Moreover, all the keys were sent as a single string, which is
unconvenient for translation and requires useless parsing in the code.

Use an array of strings instead, which is simpler.

There is a change to the archiving format, instead of storing the whole
keymap, only its name is stored. For backwards compatibility, if we
detect "ln" at the start of the string we use scientific mode.

DeskCalc: Live update base color again

... but only if you don't have a custom base color set.

Was broken trying to fix color drop regression in hrev50428

We don't want your custom Deskcalc color to get
overridden accidentially.

If you have dropped a custom base color and you want live
updating to work again, drop the current panel background
color.

Fix BAboutWindow lifecycle

BAboutWindow returned false in QuitRequested in order to hide instead of closing.
Not only this keeps a BLooper running for a rarely used window, but it also
prevents quitting an application in the window was not destroyed first.

* Remove aforementioned QuitRequested method,
* Add a static GetWindow method that returns the existing about window, if there
is one, or creates one if there is not. A boolean can be set to tell the caller
what happened,
* Adjust all callers to use that new method, instead of managing the window themselves.

Set the about window object to NULL on close or quit.

Pass the BHandler object that opened the about window to BAboutWindow.
When the window closes, send a kAboutWindowClosed message back to the
handler. This allows the handler to set the variable to NULL.

Implement the new about dialog constructor in all apps that use it.
Remove the old constructor. This now works reliably for all cases I
tested without crashing and does the right thing on close. The setup
and teardown is a bit more complicated than I wanted though.
Unfortunately this seems to be necessary when not using a BAlert.

Fetching the app icon does not work reliably yet. This is because for
replicants the app may not be running. I may have to pass the icon in
instead of grabbing it from the signature.

WIP: Create the about dialog once, hide and show, Quit() when object is destroyed.

Modify about window to take an app signature.

* Grabs the app icon and version from the resource file.
* Allow you to specify the copyright holder instead of hardcoding
"Haiku, Inc."
* Support multiple extra copyright fields.
* Modify BAlert to take a custom icon.
* Set the custom icon of the BAlert to the app icon.
* Also set the app version.

* Convert BAboutWindow to derive from BWindow
* Place a 128x128 icon and fill out a scrolling BTextView
with options such as authors, version history, copyright,
license, etc. Still needs some work but is coming along.

* Add the word Version to the version line, i8n'ed of course,
and tweak the info box and default sizes.

Fix radian/degree mode toggling bug in Deskcalc

I overlooked this problem in my last commit...

If you select the current angle (radian/degree) mode from the menu
it toggles the angle mode, fixed this to make it keep the current
mode.

Implement degree mode in DeskCalc.

Default is radian mode, You set the option in the right click menu
like the other options.

Note: degree mode does not affect hyperbolic trigonometric functions.
This is how Mac Calculator, Windows Calculator, and Google Calculator
work.

Update Deskcalc's right-click menu options.

If CalcView is embedded as a replicant on the desktop it's parent
window is not CalcWindow. Furthermore, it can't switch between
compact, basic and scientific keypad modes, you are locked in tox
the one you picked at the time you embeded the view into the desktop.
So, I have updated the right-click message to reflect this reality
by taking away the keypad mode switching options. You can still
set auto num-lock and turn beep on and off (theoretically someday
anyway) but the CalcView receives these messages instead of
CalcWindow. So, these 2 options now work in the case of a CalcView
embedded in the desktop at least.

Add a scientific mode to Deskcalc.

Deskcalc already contains support for all the functions in scientific mode
but up until now you had to know what they were called and type them in to
figure them out. Scientific mode gives you access to most of the available
functions via buttons.

Pushing one of the the scientific mode buttons inserts the function name
along with an innertube () at the current cursor location. If you have some
text highlighted when you push a scientific mode button it will put that
text inside the innertube. So you can type 0.5, then highlight the text with
the mouse, and then push the sin button and you will get sin(0.5).

The contextual menu has been altered to support the new mode.
Instead of having a single show keypad option in the contextual menu there
are 3 new options instead. Compact mode, Basic mode, and Scientific mode.
Basic mode is the default mode showing the basic keypad. Compact mode is the
same as show keypad turned off, showing just a bare text field. Scientific
mode is the new mode which adds buttons for the different transcendental
functions and constants that Deskcalc supports. You can also use Alt+0, Alt+1,
and Alt+2 keyboard modifiers to switch between the modes.

In addition to accepting the word 'pi' for the circumference of the unit
circle, Deskcalc now also recognizes the UTF-8 character π which has a
dedicated button in scientific mode. I also changed the parser so that
lowercase 'e' always means Euler's number and uppercase 'E' always means
'times 10 to the' so 1E5 means 1 times 10 to the 5th.

Another small tweak I did was to adjust the minimum basic mode width so that
the window is flush with the tab.

I also renamed fColums to fColumns, took out some spaces and other style
changes and bumped the version to 2.2.0.
