Add URL schema examples to README
Also reordered some of the sections for a more logical flow
Add trove classifiers to setup.py for python versions
Add setup.cfg for wheel support
Fix cleardb test
Remove Travis CI unsupported python version
Per docs http://docs.travis-ci.com/user/languages/python/ "Travis CI support Python versions 2.6, 2.7, 3.2 and 3.3"
Although I find `assert url['PORT'] is None` more pythonic, PORT is set in the main script via `'PORT': url.port or '',` so, we are obliged to use checking for '' in our tests.
Add MySQL (GIS) support
Add mysqlgis url scheme which uses django.contrib.gis.db.backends.mysql, add a test, and update the README.
Ability to set different engine
Added spatialite backend
Add "pgsql" as a PostgreSQL URL scheme.
This patch fixes the way urls are parsed to support blank passwords, usernames, hostnames...etc. This is particularly important in dev environments with Postgres, where blank passwords currently don't work
