Dode common in plugins using schema have been factorised in pubsub schema plugin, and filters users in tickets handling have been renamed in a more generic way and put there too.
"reporter*" fields in tickets have been renamed to "author*" as it is a more generic term which can be used elsewhere.
The use of new utils.partial function make easy the creation of simple plugins using schema.
those methods are high level methods specialised for tickets.
ticketsSet will use default tickets node if node is not set, set "created" and "updated" fields, create comments node if the ticket is new, and associate it with "comments_uri" field.
ticketsSchemaGet is like getUISchema with node defaulting to tickets default node.
- "schema" attribute can now be specified directly as a data_form.Form (reparsing it will be avoided in this case)
- new "deserialise" parameter allows deserialisation from unicode strings in sendDataFormItem
- values can now be an iterable or directly the value to use (it will be put in a list automatically in the later case)
- "id" is now put directly in XMLUI's "id" field instea of "_id"
3 new methods are introduced by this patch:
- psSchemaUIGet to get XMLUI from node schema
- psItemsFormGet to get items as XMLUI when we know they are data forms
- psItemFormSend to set item from values when we know it's a node with schema. For this method, schema can be specified, and if it is not it will be retrieved from node (which imply an additional XMPP request)
