-- new in version 1.32:
--
-- examples changeOptionFriends ('add', 'player1')
-- -> same as:

--
-- examples changeOptionFriends ('add', {'player1', 'player2', mobID})
-- -> same as:

--		changeOptionFriendMob ('friend', 'player2', 'add')
--		changeOptionFriendMob ('friend', mobID, 'add')
--
-- examples changeOptionMobs ('remove', {'mobname', mobID})
-- -> same as:
--		changeOptionFriendMob ('mob', 'mobname', 'remove') 
--		changeOptionFriendMob ('mob', mobID, 'remove')
--
-- examples changeOptionMobs ('list')
-- examples changeOptionFriends ('reset')
--
-- second parameter can be a single name/id or a table of names/ids
