Figure out Integer Story

[thehydroimpulse]

I'm leaning on having a powerful integer story. Moon is going to be optionally typed with the ability of having strong integer support. This is quite important for games and such. By default, a signed-64-bit integer will be used. Otherwise, you can specify the type: 9u8, 5555u64, -1233i64.

There also needs to have support for negation in the integer lexer.
