Fixed overbid AI bug

AI had the ability to bid more than the number of dice that existed on
the table. This has been fixed to always only allow the AI to bid put
to the total of the dice on the table.
Fix to prev next buttons on spinners.

The previous and next buttons on the spinners didn’t work with a list
that was 1 or 2 items long.
Modified bid UI to limit bid selection

Bid UI will update to show only valid bid options.
