Fixed bugs in the updating of the listboxes. Removed the Close button and moved the status bar to the same row as the buttons.
User interface changes:
* Show a smaller window if no dups are found.
* Add a spliter between the two listbox so that they can be horizontally resized.
* Changed the menus:
 - Removed the submenu ("Find duplicates"). It was unnecessaryto begin with.
 - Place an item in "tools", "appmenu", "bookmarks" and "bookmarksBMB".
Remove unused locale entries
Bump version number
