Gvfs Backend support

At long last gvfs has support for things like ftp/smb/bluetooth amongst others. These aren't perfect but basic functionality is there.

This means that you can now browse your phone send images/file from one device to another all from the comfort of the bluetooth applet (hooray \0/).

This was about the only thing I found that was missing from the gvfs/gio duo. Now it's included I'm a lot happier with my desktop :)
