Refactored basic widget class
there are still quite a few problems:
- the tests are not complete
- the mechanims of sending signals between views/controller needs be more flexible
- there is too many levels of subclassing (ie. paginated versions)

Added utility class for better testing
- rewritten the results widget (considerably; using 'all' handler)
  - improved the UI and fixed pagination (now it's very robust)
  - added tons of tests
made small display changes
