game is merge happy (emu only?)

[lowagner]

Sometimes the code merges more than one block at a time. For instance, if there is a row:
16 8 8
and you press left, you get 32 at the far left, instead of just 16 16, which is the standard 2048 rule.

perhaps that is just the button being registered twice, when the player might only want one. If so, this could be helped by the new press a button, unpress a button code ;).
