ANTLR prints errors for methods containing "$"

Run the build, and you'll see errors like this:

error(114):
/Users/alexeagle/IdeaProjects/noop/src/main/antlr/noop/grammar/NoopAST.g:48:2:
attribute is not a token, parameter, or return value: eq

ANTLR expects all "$" chars to denote a replacement token from the
production line - but many Scala methods contain dollar signs in their
compiled names, like $plus$eq for the "+=" method.

The build succeeds anyway, so this is just annoying.
