Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

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.

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. :^)
