Merged requested to merge dfazzini_test_check_DVoptions into master
Adding a specific python unit test for comparing the DVoptions with the ApplicationOptions class in PyConf in order to track any changes in the latter and consequently update the DaVinci configuration.
I also removed the full list of DV options from the reference files in order to make them more stable with respect to changes upstream.
Finally, I also removed a few reference files that were not used by any qmtests.
Addresses issue #29 (closed).
