Pokergame.js  & FlopGame.js   call/check/bb fix

<b>Check/Fold checkbox not working (0.02BTC Bounty) #2</b>

These changes will fix issues listed below, with the exception of #1, I thought it was appropriate to show wait for bbcheckbox when sitting back in but I made sure check/fold does not show. Comment out line 272 if you want it hidden on sit-in state.  Let me know if you have any questions.

1) While playing and clicking sit out then sit in the check/fold and wait for bb options show (can sometimes be 1 or other)
2) When refresh browser while in a hand but not your turn the wait for bb option shows.
3) Both options show when a game ends, as in all players sit out and no hand dealt.
