Added some more drawing commands, and fixed a bug that made the parser
choke when assigning to global variables (don't worry, those aren't the
type that earned a bad rep, but rather the kapuro version stored as
files, and you'd better appreciate the fix because it involved royally
mindfucking Eclipse, then regenerating the Eclipse files and relaunching
it, although the functionality won't be used much outside of saving and
shitz)
