BColorControl: Remove fOffscreenView pointer

...and rename fBitmap to fOffscreenBitmap to make it more clear what it is.

We don't need to save a pointer to both the offscreen bitmap and
the offscreen view, just the bitmap. We can access the view by calling
fOffscreenBitmap->ChildAt((int32)0). This gives us back a _reserved private
variable slot.

In the (unlikely) case that _InitData() is called with offscreen = false but
the fOffscreenBitmap is not NULL, delete fOffscreenBitmap before
setting it to NULL so that memory is not leaked.

Style fixes to IK, focus on docs

BControl subclasses: Override SetIcon()

... and implement Perform() action for potential later use.

ColorControl: Implement keyboard navigation

Implements enhancement described in #9819

This feature works pretty much as it did on BeOS R5.

When you focus on the color control, the border is drawn blue and
the dot on the red ramp draws as an outline to show that it is
selected. You can push the up and down arrow keys to navigate to the
previous and next ramps respectively and can push right and left to
increment and decrement the color value of the selected ramp.

Clicking on the control no longer gives it focus.

In BeOS the left and right arrows would increment and decriment by 5,
on Haiku they increment and decrement by 1, but, by holding down the
key for a second or so the increment value increases to 5 allowing for
both course and fine adjustments.

On a technical note I split the int32 fFocusedComponent member variable
into 2 int16 member variables, fFocusedRamp and fClickedRamp. I did this
because I needed an entra variable, and can't change the size of the
class without using up another reserved member variable slot. int16
should be more than enough for these variables as they store an index to
the currently focused or clicked on ramp (0-3). Please someone chime in
if this is not okay for FBC in some condition I didn't think about.

BColorControl: Introduce a _PaletteFrame() method

... eliminating duplicate code.

BColorControl: Size text rect based on font size

* Also change kMinCellSize from a uint32 to a float so that it can be used
with std::min() and std::max() instead of min_c() and max_c().
* Set the text controls sizes and margins based on the font size. Also rework
_TextRectOffset() so that it will get the right spacing from by dividing the
palette frame by 3.
* Replace bare numbers and refactor with calculation or magic constant.
* Create a private method _TextRectOffset() which calculates and
returns the vertical text rect offset to use based on the font size.
* Replace 2.0 with new kBevelSpacing constant where appropriate.
* fPaletteFrame calculation in _LayoutView() was refactored but should
not have changed.

BColorControl: Create _SetCellSize() method

...eliminating duplicated code.

BColorControl: Style fixes

* Update copyright in header, add my name, alphabetize.
* Rename _ColorRamp() to _DrawColorRamp().
* Rename update parameter to updateRect

Fixed for 80 char limit.

Implemented palette mode and fixed bugs listed at ticket #1701. Thanks

* rewrote ColorControl.h
* removed unused stuff.
* shuffled methods around in the source, so that you don't have to jump so far
when working at a specific thing (ie. all draw functions are grouped together, ...)
* ResizeToPreferred() should now work as expected.
