#80 monitor profiler UI - indicate measurement success

[Hal Engel]

from Craig Ringer - ringerc

In the main Monitor Profiler it'd be very helpful if some indication was given as to whether or not valid measurement files have been created/selected. Currently there's no difference between "before measurement run", "measurement canceled" and "measurement completed
successfully".

Yes this is a know issue that does need to be worked out.
