Code Issues Proposed changes

Add hacking check for assertEqual HTTP code

Browse Source 
Add a hacking check for wrong usage, like:
  assertEqual(observed.code, webob.exc.HTTP**.code)
the correct usage should be:
  assertEqual(webob.exc.HTTP**.code, observed.code)

- [N330] Use assertEqual(*empty*, observed) instead of
assertEqual(observed, *empty*)
- [N331] Detect wrong usage with assertTrue(isinstance()).
- [N332] Use assertEqual(expected_http_code, observed_http_code) instead of
assertEqual(observed_http_code, expected_http_code).
