1.0 beta
- first public release

1.0 beta 2
- moving files in the preview list doesn't move their new dates anymore
  (sorting suddenly makes sense)
- old dates in the preview pane are reread after successful redating

1.0 final
- added support for file lists passed from Branch view and Find files -
  Feed to listbox

1.01
- the time in the Preview wasn't shown if set to 00:00:00 (exactly
  midnight) because the function I used - datetimetostr - cut it off in
  this special case. Christian suggested it should always be shown, so
  after a short research I changed the function to formatdatetime which
  works as desired
  
1.02
- a randomize option has been added. By pressing R the values for the
  currently selected chcekboxes are randomized. The intervals are
  <Start; Start + Inc> for years and <Start; Inc> for the rest
  
1.03
- the automatic updating of the Preview is very slow for a large number of
  files (~200), therefore I added an option to toggle it by pressing U
