Implement Jeopardy cashout

This adds integration between Watbot and the Limnoria Jeopardy plugin.
If a game of Jeopardy ends, Watbot will parse the finishers message and
pay a small share of the Jeopardy price money in the form of Watcoins.
To avoid abuse, only Jeopardy finishing messages from authorized bots
are considered. An IRC user is considered an authorized bot if the
hostmask matches one of the configured bot hostmasks, and if the
nickname is configured for "jeopardy" in the newly introduced bot games
configuration.
