Ed_ b8e1aa6eb7 WIP : Fixes and other changes
* Number literals weren't getting properly lexed
* Fixes for compiler errors with Unreal Engine configuration.
* Support for "post-name" macros in parameters
* Support for variables initializing directly using constructor syntax.
* Explicitly added inline keyword to header inlines for compiling compile library in multiple translation units.
