f0a6b42066 Move common Application build steps into their own Makefile.common 
Further consolidation is of course possible, eg the Games/ programs
follow the same rules more or less.

8247dad540 PaintBrush: Allow RGBA32 to use the bucket and spray tools. 
Eventually I'd like to do some kind of bitmap layers, and we definitely want
alpha channel support then, so let's just not paint ourselves into an
uncomfortable corner early on. :^)

b529b4a3e6 PaintBrush: Add support for opening files. 
Obviously this only supports whatever PNG files that load_png() can decode
at the moment.

5aefd7f828 PaintBrush: Implement a thickness setting for the pen tool. 
Painter gains the ability to draw lines with arbitrary thickness.
It's basically implemented by drawing filled rects for thickness>1.

In PaintBrush, Tool classes can now override on_contextmenu() to
provide a context menu for the toolbox button. :^)

502c54e39a Add a simple spray fill tool 
Could do with some more tweaking no doubt, and it'd be nice to have a
circular spray, but this is better than nothing.

cf17e385b5 PaintBrush: Allow editing palette colors by ctrl-clicking them. 
Maybe the ColorDialog class could be fashioned into something generally
usable in LibGUI, but for now it lives in the PaintBrush app. :^)

dcbddb4f8c GraphicsBitmap: Provide templated versions of get_pixel() and set_pixel(). 
If we already know the bitmap format used, we can use these functions to
bypass the format checks and go straight to pixel manipulation.

9443957c14 PaintBrush: Speed up the bucket tool with smarter use of Vector. 
Put together a pretty well-performing queue using a Vector and an offset.
By using the new Vector::shift_left(int) instead of Vector::take_first()
we can avoid shifting the vector contents every time and instead only
do it every so often.

Maybe this could be generalized into a separate class, I'm not sure if it's
the best algorithm though, it's just what I came up with right now. :^)

e9c021de92 PaintBrush: Implement a naive but working bucket fill tool. 
I've used a SinglyLinkedList<Point> for the flood fill queue, since Vector
was death slow. This could definitely be made faster with a better algorithm
and/or data structure. :^)

56cbe15033 PaintBrush: Factor out the pen tool into an actual PenTool class. 
Also add a Tool base class, and an empty BucketTool subclass which is the
next thing to implement.

f86b1bdca1 PaintBrush: Add a PaletteWidget to allow color selection. 
Also use different colors for left/right mouse button. :^)
