plugins xep-0060, xep-0163, xep-0277, groupblog: bloging improvments (huge patch, sorry):
/!\ not everything is working yet, and specially groupblogs are broken /!\
- renamed bridge api to use prefixed methods (e.g. psSubscribeToMany instead of subscribeToMany in PubSub)
- (xep-0060): try to find a default PubSub service, and put it in client.pubsub_service
- (xep-0060): extra dictionary can be used in bridge method for RSM and other options
- (xep-0060): XEP_0060.addManagedNode and XEP_0060.removeManagedNode allow to easily catch notifications for a specific node
- (xep-0060): retractItem manage "notify" attribute
- (xep-0060): new signal psEvent will be used to transmit notifications to frontends
- (xep-0060, constants): added a bunch of useful constants
- (xep-0163): removed personalEvent in favor of psEvent
- (xep-0163): addPEPEvent now filter non PEP events for in_callback
- (xep-0277): use of new XEP-0060 plugin's addManagedNode
- (xep-0277): fixed author handling for incoming blogs: author is the human readable name, author_jid it jid, and author_jid_verified is set to True is the jid is checked
- (xep-0277): reworked data2entry with Twisted instead of feed, item_id can now be specified, <content/> is changed to <title/> if there is only content
- (xep-0277): comments are now managed here (core removed from groupblog)
- (xep-0277): (comments) node is created if needed, default pubsub service is used if available, else PEP
- (xep-0277): retract is managed
