Benoît Minisini c9ca5ab982 [CONFIGURATION] 
* NEW: Update copyright year to 2013.

[GB.FORM]
* NEW: ImageView is a new control that allows to view an image inside a 
  scrolled view, at different zoom levels.
* BUG: FileProperties now works correctly if 'gb.desktop' is not used.
* NEW: The FileProperties preview tab now uses an ImageView control and has
  a toolbar to zoom the preview.
* BUG: Add the 'linux' and 'gnu' icon in the stock icon list.
