Berthold Stoeger a455b32e02 Filter: implement reset filter
Move initialization to a separate function and connect that to the
reset button.

Two points of note:

1) Reseting the text-fields causes signals. Thus, signals have to
   be ignored during reset. Do this with a new flag.
2) To make reset of the from-date work, the from-date has to be
   initialized to a distinct value. Setting a default-constructed
   QDateTime leaves the widget unchanged.
