- Add lottery and plain round robin cpu policies. I didn't test

them extensively, mind you. Closes task #14.
- Added documentation for each cpu policy
- Manage extra-exception into PythonCPUPolicy (when the .py
file doesn't contain a similarly named class)
- Update exception output in GuiBuilder to make it slightly
more descriptive
