thunderbolt: new panel for device management
Thunderbolt devices need to be approved before they can be used. This is done via the boltd system daemon and gnome-shell. The new panel enables the user to manage thunderbolt devices, i.e.: - forget devices that have previously been authorized - authorize currently unauthorize devices Additionally authorization of devices an be temporarily disabled to ensure no evil device will gain access to the computers resources. File starting with "bolt-" are copied from bolt's source tree and currently correspond to the bolt upstream commit with the id f22b1cd6104bdc2b33a95d9896b50f29a141b8d8 They can be updated from bolt via the update-from-bolt.sh script.
