mod_csi_muc_priorities: Allow setting the default priority for mucs to low Move the priority checking after the mention check so that if there is a mention we return true. Add an option to the form to set the default priority to low. Return `nil` in cases where we determite that the priority should be high, as with `mod_csi_simple` this causes normal MUC messages to be marked important while allowing mod_csi_grace_period and unneeded messages to be queued.
