* Minor shader formatting

* Particles now have proper glow
 * Fixed bug where references to static variables would stay in ParticleEmitter and particleInfluencer, causing havoc
 * Fixed warning in InputManager when using ScreenshotAppState
 * TestEverything now uses TangentBinormalGenerator, since before there was no tangents for the floor
