Modchat: Fix access denied reply (#2664)
Modchat: Fix access denied reply (#2664)

Before, if a RO (not a global leader or up) tried setting modchat, it would say: "/modchat - Access denied for setting higher than +."

Now, this fixes that by checking what permission that user actually has in the room, as in if they're a roommod (up to +) or roomowner (up to #).
