Fixed repo URL and added PyPI classifiers

The URL for the repo currently gives a 404, so it wasn't easy to find this repo via PyPI.  I've fixed that.

I also added classifiers for PyPI so users will know that the package works with Python 2.7, 3.2, and 3.3 (at least I assume it does, by the looks of PR https://github.com/Aquasys/django-jasmine/pull/6 -- ironically, this package has no tests!)

BTW, is there a rationale for having the issue tracker turned off for this repo?
