Some of the textures in the textures configuration file use sprites
as patches. Because of this, the build system was inserting extra
dummy entries for these "missing" patches. Handle this corner case
and do not insert dummies for sprites. Fixes#40.
Python 3 makes a number of changes to the language and breaks backward
compatibility with Python 2 in some places. This change updates the
Python scripts used in the build system to work with Python 3,
although the updated scripts still run in Python 2 as well. Most of
the changes are minor; the biggest changes are to the palette /
colormap generation scripts.
