Pokergame Dealing Fix

If you quit out of the poker game while dealing, it switches to the draw option when you try to play again, this removes the function that causes this on quit.

to test:
1. open pokergame
2. press deal
3. quit while dealing
4. replay, after a couple of seconds the options change

this just resets the callback so this doesn't happen, another option is to remove the quit option while dealing, let me know which is better.
