This commit is mainly as a result of creating DN entries and improves some backend functions:

* Enable creation of new entries,
* Change all our ajax frames to go through /frames URI instead of /dn,
* Add our frame command to the encrypted DN,
* Automatically redirect to root URL when selecting a tree item and currently in another path (as a result of a prior POST activity),
* Some validation improvements DNExists/HasStructuralObjectClass
