Renderer-based particle system (#25)

Browse Source 
* A WIP particle system

* - Some more particle refactoring
- an attempt to fix things that went wrong
- trying to integrate fog onto particles (which is currently wrong)
- qpal.h committed (oops)
- Attempt to separate particle rendering from particle moving for future optimization/refactor
