Beginning work on event handling. Basic handling of key presses
Events: Peek SDL_WindowEvent
Events: Peek should now be total over all event types (though event bodies are very much TODO)
RWops: Use 'close' function pointer with SDL_RWops struct as finalizer
Events: use mkPosition and mkSize. Remove dead code
Handle SDL_QUIT events
Events: Handle fields of SDL_TextInputEvent
Events: Handle SDL_MouseMotionEvent
Events: Handle SDL_MouseButtonEvent
Events: Handle SDL_MouseWheelEvent
Remove a TODO now that I have read the documentation
