Adds pessimistic locking capabilities to the redis gem. Since these capabilities are utilized client-side, all clients must use this gem and follow the order of lock => make changes => unlock in order to obtain maximum safety when modifying sensitive keys. Tested with redis-server 2.0.4 and should work with all versions > 0.091.
