Simple non-antlr AT parser

[lukebemish]

Antlr, unfortunately, is Not Great. At this point, it's beginning to consistently be badly-supported by gradle and IDEs alike; furthermore, it's not necessary at all for this use case. AT files are quite easy to parse; here, I implement a small, regex-free AT file parser that as far as I can tell is consistent with the old behavior of AT files. While it seems to run correctly on all the tests, if anyone finds an issue with my implementation, please let me know.

I feel that we should keep the ANTLR grammars around, though not in /src, likely a /extras folder or some such. This is because it may be useful to other people writing AT parsers as a reference (e.g. for IDE integration), even if it's not a 1:1 match with how they're parsed actively.

[lukebemish]

That's not a bad suggestion; added them in a extra directory.
