WIP - Broken Compile : Added pragma once and includes to all files + Parser fixes, and String improvements

Adding the pragma once and includes the files broke compilation, still diagnosing why.

- Some string functions were moved to the cpp, still need to do some more evaluation of it and the containers...
- Added support for forceinline and neverinline to parsing (untested)
- Added support for specifiers in operator cast such as explicit, inline/forceinline/neverinline, etc.
    - Before it only support const.
    - Still need to support volatile.
- Forceinline was not supported at all for tokenization, fixed that.
