Version 1.141 - Save Case and Physician Preferences Fixes

Client complained that they were having an issues saving cases. The
spinner would not go away after attempting to save a case. We inserted
some additional error checking to hopefully eliminate this.

Client has also said savePhysicianPreferences wasn't working. We
addressed this issue as well. Had to do with the way ProductSystems were
being saved with the savePhysicianPreferences call.
