Added "rathole" command

Added "rathole" command to deposit amount over $1000 to bankroll or
withdraw amount under $1000 if cash is less than that. Added to
TexasPoker and Blackjack. Updated texaspoker.help and blackjack.help to
reflect the new command.
Cleaned up "rathole"

Removed new transfer method. Calling findJoined twice possibly not worse
than repeating code..
Minor formatting changes

Tab spacing.
