Bastion codebase updated

Just updated all my branches to the latest codebase, and they all seem to build and run fine.

I'm going to try to build against the latest MonoGame assemblies now, though I think there is a bunch of discrepancies between Windows/Mac/Linux versions of the assemblies (I'm on a Windows box for now). Building against the assemblies will most assuredly fail anyways. I'm just going to keep trying to build and change code until I get something running, or until I hit a wall with Effects and get all the shaders converted to GLSL.
