Subject: [PATCH] Make rate limiting penalties less severe

* The max rate limit penalty is now 20 instead of 5 making the bot
  more responsive without making it flood; this seems like a
  reasonable value but may need to be further tweaked
* No longer unconditionally add `1' to penalty to decrease the
  likelihood of the queue being saturated and never getting further
  than popping the first message
