Minor changes.

Added grand total to the output of "gamestats" command when no size is
given. Changed camel case to '_' for a couple of variables. Added
identification check for "player" command.
Fix for getting game totals.

Fixed upper limit of range in get_game_totals().
Added MIN_PLAYERS setting.
Add feature for wait time added for each !join

Ineffective by default because the wait time is set to 0 in the default
configuration file.
