simplify cmakelist options for configuring python
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Unify the existing cmake variables relating to python features.(enable python programmable filter, enable testing through python, enable python wrapping of the server for pvpython client, enable python client window in gui). Make one non advanced cmake variable that will set from none, medium, or full wrapping. Make advanced entries that turn each feature on or off.
