Extend filter in Tobject::all for timestamp meta data

Issue description

It should be possible to search for topics created/modified in a given time range.

Developer comments

Tricky. MySQL timestamps are in UTC. When they are queried in a filter the normal behavior of interpreting timestamps in session time is circumvented by setting time_zone to UTC before the query (and setting it back afterwards). When the admin passes a string, it is interpreted as UTC. But passing DateTime allows complete control by setting the timezone accordingly.
