Configurable sections are broken ("configuration cannot be displayed because it was last edited by Admin who doesn't have permission to edit this page")

Configurable class doesn't work with Velocity 1.7. #checkDocumentSavedByAuthorizedUser is used in a non-compatible manner, so the check always seems to return false.

#findNamesOfAppsToConfigure is also a bit wrong, but it works since the actual and formal parameter names are the same.
