Special-case PMs of the form foo:/

[fndax]

The bot currently parses messages starting with a word followed by a : as commands with role specified before the :. This isn't ideal when the user is in deadchat/wolfchat, because it means that hyperlinks (most notably wiki links) can't be sent without prepending something to the message (the bot thinks you're sending a command with a role of "http" or "https").

Special-case role:action messages where the action starts with a / so that the bot doesn't attempt to interpret them as actions and just sends them to foochat instead.
