1.4
----------------
New features:
- Refactor addition of criteria to stick inside ``INavigationRoot`` in querybuilder. Added a simple ``IQueryModifier`` interfaces expecting a query and returning a query. Iterates over all sorted utilities providing such an interfaces and calls it right before the query is parsed. Code to add the ``INavigationRoot`` stickiness was moved to such a query modifier.
