Modified PhysicsTools/Utilities/scripts/edmPickEvents.py

The script edmPickEvents.py is used to quickly pick events from datasets if they are available  locally OR run a grid job if they are not available locally. Hence this modification was needed. I have tested the script and it works fine. Kindly accept the request and make incorporate it in other releases.

The details are as follows:
I have changed the python script PhysicsTools/Utilities/scripts/edmPickEvents.py to replace scheduler from "condor" to "remoteGlidein" and moved the reference to useServer outside the "if" loop.
