Also, a couple more minor bugfixes are included for /f home payment giving the wrong message, player/faction descriptions being wrong for console messages, and potential NPE in new faction leader promotion routine if faction was permanent with no current leader.
New permissions:
factions.leader.any - allows use of /f leader on any player in any faction
factions officer.any - allows use of /f officer on any player in any faction
factions.join.any - allows player to join any faction, bypassing invitation process for closed factions (the same as players with /f bypass enabled can do)

Note: for proper faction bank support, if you're using iCo5 or EssentialsEco, I recommend waiting for Vault 1.2.5 to be released which addresses faction account creation issues related to those.
