- Added still more error checking to PythonCPUPolicy. But the code which calls its methods should be updated to handle the new exceptions... 

- Added a base class for cpu policy exceptions to make simpler their catching
- Implemented all numeric fields in dialogs with spinboxes, with bounds checking
