+ * #1608 Quickfix for problem with DateDiff on SQL backend. I have to rethink this solution, but due to the short time, this should work.

* Minor update for sorted(). Now ignoring any category search if "DoNotShowWithCategory" filter is activated.
* Fixing uninitialized member variable, caused crash of backend
