Added an asynchronous resource loading mechanism through App_GetResourcePath and App_ResourceLoaded. Added stb_image.h and used it to parse a .png file loaded from the server and upload it to app.testTexture. There is some ugliness around the edges images with transparency, probably caused by something pre-multiplied alpha related.
