Add support for using Bitmaps as textures
Resolves #103
Hello! Quick and to the point, this comes exactly as described. 🙂 No screenshot today as there is obviously no actual visual difference between textures loaded from either a PNG/JPG compared to a BMP.
While BMPs, or at least the relativiely simple variant OLives implements, do not support alpha transparency, that is not really a problem as the only planned use case for now will have them serve as thumbnails for saved games. I still have to work out some kinks for that, but overall the entire save game topic (including the Bitmap support) is progressing nicely. Byeee!
