Minor refactor, added optional recursive dups for ast, ...

Browse Source 
- Added support for anonymous structs.
- Gave Token_Fmt::token_map its own static memory.
- Minor natvis fix for CodeBody
- Renamed ESpecifier::Static_Member to just Static (acts as a general use case) specifier option
- Setup the lex token array with a configurable arena allocator.

Two major things left before V0.3-4:
- Attribute and Module parisng support with base case test
- AST serializtaion strings get a dedicated slag allocator.
