[antlr-interest] grammar to latex

[Ana Nelson]

The red boxes are where the grammar detects an error in syntax. (As I said,
the grammar isn't quite finished yet, so those should go away, at least for
valid ANTLR files.)

Regarding automatic linebreaks, I don't think it's currently supported in
pygments, but it should be possible to implement. I know for java code it's
almost a necessity, I've done it by hand before and it's no fun.
