Downloads folder & patch-1 by letscape

patch-1 by @lestcape:
- Everything is translated by cinnamon directly into your language, used for all languages.
- The screen saver now works well.
- When not selecting an option displays the icon /home/user/.face, ie the icon for your user account.
- The shutdown options icon now also show itself.
- Compatibility with ubuntu 13.04 and not need the gksu command.

Small addition from me:
+ Downloads folder on right panel.
