Added --autostart mode and install FDO autostart file

--autostart mode currently only uploads queued keys, but it will later
be expanded to do more. Including checking the BackupRecord for problems
when necessary.

The autostart file is installed by keysafe --backup, so that when keysafe
is installed with stack, and used, it will make sure it autostarts in the
future.

The autostart file is installed by the Makefile too. This will later
let --autostart check for keys that have not been backed up and prompt
about backing them up. This way, the user won't need to remember to run
keysafe to back things up.

Reused Utility.FreeDesktop from git-annex, and had to add some stuff it
depends on.
