Updated README to reflect that alternatives must be strings.
Add redis failover solution

Due to the fact that redis has no autom. failover mechanism, it is now
possible to switch on 'db_failover' config option, so that 'ab_test' and
'finished' will not crash. 'ab_test' always delivers alternative A (the
first one) in that case. It's also possible to set a 'db_failover_on_db_error'
handler (proc) in the config, for example to log these errors via
Rails.logger.
