Call updateTorrentNumbers() once per every model refresh, not once for every row changed

Browse source 
Torrent numbers were recalculated on every dataChanged() signal. The previous commit
greatly increases the number of dataChanged() signals.

HEAD^^:
    Total wall clock:                 97.069s
    updateTorrentNumbers() time:       0.033s

HEAD^:
    Total wall clock:                 96.132s
    updateTorrentNumbers() time:       0.179s

HEAD:
    Total wall clock:                 95.535s
    updateTorrentNumbers() time:       0.047s

After this commit the time of updateTorrentNumbers() is (almost) back to
the level that it was in HEAD^^.
