Only permit one instance of GParted to execute at a time

Browse source 
Only one partition editing tool should be in use at any one point
in time.  If more than one is in use concurrently, then data loss
might occur through operations on common partitions or partition
tables.  As such, prevent multiple copies of GParted from running
at the same time.
