SiENcE's moue driver

ml (there is one in OpenDingux too) is handy for some games.
We should consider adding a mode to SDL so that if SDL_ShowCursor(SDL_DISABLE);
is NOT called mouse emu mode could be engaged (i.e. and not feed cursor key
events). We may be able to pull pieces of the Dingux/OpenDingux driver code out
for re-use.
This may not be practical, or useful, so low priority.
