Report time taken to complete search.

A nice feature would be to report the time when a search completes or is cancelled. Currently, catfish only show "X files found" in the status on the bottom. It would be great to show "X files found in Y seconds".

Currently, I am trying to compare performance search methods for debugging reasons, and I have to start a timer independently and be ready to stop it when the search end, which is not exactly professional. 😄
