Allow easy mounting of LUKS volumes in usbvm for backups

Run this nice GUI mounter for LUKS volumes attached to usbvm. This should then allow to make backups to a disk attached to an AppVM fully using GUI from Qubes Manager. Currently I need to manually start term in the usbvm, do cryptsetup luksOpen, then mount, and only then I can use the Qubes Manager GUI to choose backup location.

Perhaps implement the same worflow as when handling devices attached to Dom0 -- populate the "Device" combolist with the devices from the selected VM. This should also imply that we first choose the Target AppVM, and then the device --> replace the order of the fields to have AppVM selection first (at the top).

On my machine, file selection dialog (that running in VM) have device list on the left, where I can click "10 GB Encrypted volume", then enter the password and select file/directory.
Perhaps this do not work when disk do not have partition table (i.e. LUKS directly on /dev/sda) - this causes problems with a lot of disk management tools.

Indeed, putting the LUKS volume on a properly formatted disk (i.e. putting it on /dev/sda1 instead of on /dev/sda) solves the problem with GUI-based mounting.

One thing still left, however, is to offer the user an easy way to unmount the volume after completion of the backup. Perhaps the easiest and most convenient way would be to display the same file manager window (which was used to select the volume at the beginning) after the backup finished, together with an information to the user: "Backup has been completed, please unmount your backup volume."
