Nativs support for gen::AST, fixes & update to library, getting gen_array working...

Browse Source 
token_fmt returns StrC now. Did some fixes so it can properly function now!

Lots of changes to the Array non-parsed implementation.
It shows no errors in the edtitor static analysis, however I haven't tried it yet.
Unfortunately have some friction with how I would like to set it up like with everything in C++...
Can't inherit from ArrayBase to provide the common members to all Array defs, without introducing constructor complexity.

I may be open to using constructors in the future, depends on how I feel when trying out the context pattern used in jai and odin...
