Fix to inability to play more than one game on one table; other fixes.

A set of nasty bugs prevented the table from being to cyclically play

Some other under-the-hood changes
have also occured to lessen the amount of data that needs to be
synced slightly, remove dead code,
improve logs, and similar features.
