plugins/mod_dialback.lua @ 191:e64c8a44060f

Fix s2s once and for all - Moved dialback to the new mod_dialback (mostly). - Modules can now supply a list of origins to handle to add_handler - Modules can now handle and process any stanza, overriding the core - Modules handle non-jabber:client/jabber:server xmlns'd stanzas
