Handle Django 1.4's use of kwargs in class-based views
Split cleaning behaviour into form

Methods like clean_title don't get called dynamically.  Have moved
cleaning logic to the form which seems a more natural place.

Introduce some new test folders.
Rename get_reviewer_name property
Rework review/vote validation

Use field validators and model clean methods instead of forms.

Include new methods for voting up and down.

Add more tests.
Switch style of form to assign fields to instance param
