Renamed entity for actors (and will be new standard for all entities/other) to 'object' -> Actor.object, Entity.object etc.
Added ColladaLoader for loading .DAE files. As this is async, i need to figure out how to either preload all assets, so they are available at runtime - or find a better way to load them into the scene on runtime.
Added entity.js  - First iteration of what should be the inherited class for ALL entities in the game (weapons, items, walls, etc.)
 - Right now defines a physical boxmesh - need to figure out how to disperse this into the common/needed types (spheres, etc.) or if they should be special cases.
 - Constructor needs some work to make it easy to use and more flexible
