mod_muc_dicebot: A thing to roll dice
Do you see what happens, Jitsi? Do you see what happens when you
make it hard for me to use a proper bot? This is what happens,
Jitsi. This is what happens when you meet a stranger in the alps!
Ahem. In all seriousness, this is more of a quick hack than
anything else. It will look for `.r` in MUC messages and if it
finds it, it'll interpret it as an instruction to roll a few
dice. Injects the results in the body of the message. Eats the
message alive if it is malformed.
