minimwatch on linux: running as daemon vs manual start (can't run multiple instances)

[simoncn]

If you have desktop integration enabled, MinimWatch starts initially as a background daemon process (not running under root), then automatically restarts as a foreground GUI process when you login.

The background process was needed in version 0.8.3 to receive commands via the named pipe (now deprecated in favour of command scripting which was added in 0.8.4). The named pipe and background process will be removed in the next release of MinimWatch.
