Reorganization of parser, refactor of parse_type( bool* ) and progression of parser docs

Wanted to make parser implementation easier to sift through, so I emphasized alphabetical order more.

Since I couldn't just strip whitespace from typenames I decided to make the parse_type more aware of the typename's components if it was a function signature.
This ofc lead to the dark & damp hell that is parsing typenames.

Also made initial implementation to support parsing decltype within a typename signature..

The test failure for the singleheader is still a thing, these changes have not addressed that.
