Title: Minor cleanup

Several things. See commits for full details. Some highlights:

* Made more methods `const`.
* New SDLSurfacePtr type which is a smart pointer version of SDL_Surface*
* New helper function LoadSurfaceFromFile to load an SDL_Surface from the file-system
* Re-enabled the fallback texture
* Added some extra methods to `vector2f`
