plugin tickets: added ticketsSet and ticketsSchemaGet methods: 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.

# FIXME: remove this when RSM and MAM are in wokkel
# XXX: the Monkey Patch is here and not in src/__init__ to avoir issues with pyjamas compilation
