Macros/Multi param function args

[bossinc]

Functions passed into macros that have multiple args will parse correctly.

Before if your macro was select * from foo where $__params(FUNC(foo, bar)) it would parse the macro params as ["FUNC(foo", "bar)"]
It will now parse the params as ["FUNC(foo, bar)"]

I also created a Macro struct to make it clear which part is the macro name and args.
