decouple the dispatcher (a key, basically) with the actions to take upon
receiving such a message. allows us to have multiple actions for one key
without weird hacks
use GenericAPIView rather than APIView in order to get some common idiom
stuff done for us. we continue to support GET and POST in
DispatchMessage, now it's just a bit cleaner. i think.
anyway if we were doing this stuff more we could/should probably create
mixins for them, but at the moment this is pretty sane i think
this moves the dispatcher functionality that used to be in the old
ircbot directly to django REST framework, which is more robust and
allows for cooler stuff down the road. this still retains the ability to
have the bot privmsg, that still happens over the XML-RPC interface,
this is just a more convenient frontend to that
