Pixel Flags 1.29 - Added weapons

So in the latest version of Pixel flags (or 'PF' as people around me have called it),  there are weapons that can be picked up around the map. They have set spawn locations, but I'll add random spawns soon. They each have different damage rates and reload times.  Also, some of the code has been optimized to run a lot faster. but It's all just shadow code for the cultured whom'st understand such references.
