PEP implementation, draft (huge patch sorry): /!\ database schema has changed ! /!\ - whole PEP behaviour is not managed yet - if the stanza is delegated, PEP is assumed - fixed potential SQL injection in pgsql_storage - publish notifications manage PEP - added retract notifications (if "notify" attribute is present), with PEP handling - a publisher can't replace an item he didn't publised anymore - /!\ schema has changed, sat_pubsub_update_0_1.sql update it - sat_pubsub_update_0_1.sql also fixes bad items coming from former version of SàT
