Added tox integration, restructured testing, tested for django 1.7
The contents of django_silky/ and silk/tests were moved to tests/, and a symlink was created from silk/tests back to ../silk so files don't need to be copied during testing
Imports in the tests were refactored to match the new structure(including tests/__init__.py
Trivial modifications were made to the test settings file to accomodate different testing environments
Updated Readme to reflect tests in django 1.7
changed .travis.yml to be compatible with the tox
Removed environment for python 3.2 from .travis.yml
Merge branch 'master' of https://github.com/mtford90/silk into tox
Merge pull request #47 from brmc/tox
