Made background of stick-figure transparent.
Add two more versions of bigBang that don't require you to specify
the width and height of the window; it uses the initial image, as
in 2htdp/universe.
Made ImageMap and ImageBuilder interfaces public, so they can actually be used.
Gave the Mode class a couple of aliases: SOLID, solid, FILLED, and filled
all mean the same thing, while OUTLINED and outlined mean the same thing.
Several methods in RasterImage (notably "save") weren't rendering
before going on.  As a result, saving a recently-constructed image
often crashed.  That appears to be fixed now.
