mod_muc_limits: Add config option to limit to join stanzas only
This is a bit more limited in pre-0.11 MUC modules, because it just
detects stanzas sent to full JIDs (which would include all presence
and nick changes).
This option is useful for setups where users are typically unaffiliated,
but trusted (e.g. if access to the room is gated through some other
means such as password/token auth).
