Multiple Mesh Support!

I finally was able to finish part of a multiple mesh setup in that we now have five primitive meshes we can use! Creating things will be much more dynamic and soon when we add environmental editing and power to objects, it will get VERY interesting :) THe only issue I have right now is a few little collision shape issues and some lagging on html5 mobile versions and those on pc and mobile that do not have gpu hardware acceleration enabled or available. 

For the first issue, I will likely code it to create collision shapes all directly from vertex points. It will be easier for the script to know and might help with performance or hurt, I am not sure yet but the goal is for an overhaul of dynamic collisions for both smaller script size and better collisions. 

For the second issue, that will depend on teh user right now. Make sure you have hardware acceleration on in your browsers! The engine will be listening for it ;). If you cant, I will still be working on maybe adding multithreading BUT that gives another concern of html5 freezing as generally html5 is not known for great multiple thread performance, in fact in many cases it freezes up for 1-2 seconds at a time so I will work around that hopefully. Thats it for now, hopefully more coming very soon!
