Fix for the menu on Mint 14 with Nemo

Jake,
There was a bug where the links to documents, pictures, etc wouldn't work in mint 14 cinnamon because nautilus is not used in v14, Nemo is. I have simply edited the command to launch `nemo Documents` `nemo Computer` etc instead of `nautilus Documents` `nautilus Computer` etc, so it opens the correct file manager. Easy fix, just figured I would save you some time and upload the fix I have been successfully using on my local machine for a while now.

Cheers!
