HOLES ARE WORKING!!!  Well, kind of.  There's a pretty stupid bug of the
character falling from a hole into the grid next to it (try
perspective_falling.xml at several angles).  I'll probably put a distance
restriction or something.
I also started the long process of documenting everything via Doxygen (use
doxygen.cfg as the config file)...Gonna be a LONG winter break.
Fixed several bugs:
-Freeform_grid not displaying correctly
-holes and launchers not esc-able
