fix tests
add django 1.4 and python 2.6 to the travis config
trigger travis build
use django bundled unittest2
attempt to improve travis speed by using cached pypi packages where possible instead of git sources for django
drop support for django 1.4, seems the serialization stuff actually does require 1.5
fix broken .travis.yml
attempt to fix serializer order test failure on python 2.6
actually serializer order doesnt really matter. ignore it in the serializer tests
fix tests on python 2.6 (seems assertItemsEqual is really bizzarro)
fix syntax error on py3, not that it works elsewhere yet anyway
