mod_pubsub: Check new role framework for node creation privileges This enables granting regular users permission to create nodes via the new roles framework. Previously this required either making everyone an admin or writing a custom mod_pubsub variant with different permission details. Previous default behavior of only allowing creation by admin is kept as to not give out unexpected permissions on upgrade, but could be reevaluated at a later time. Fixes #1324
