__PACKAGE__() as a sub, not a special token

[amiri]

I added PACKAGE as a sub, and I would like to check whether this is the right basic idea. It seems like to make it work as just PACKAGE, I need to make it something like selfLiteral in MoeLiterals or I need to provide some special keyword parser, like for subroutineCall in MoeProductions.

Hmm, are you sure it requires the parens? Perhaps making it a special token might not be a bad idea.

This current implementation requires parens, PACKAGE(). Otherwise the interpreter attempts to resolve it as a class. I will definitely work on making it a special token or adding a special keyword parser.

Excellent, thanks!
