Got tests running with tox in Django dev version.
Got http tests in basic and alphanumeric working with in-memory sqlite.
Removed duplicate dependencies to fix "Double requirement given" in Travis CI.
Fixed error that was causing docs to not build.
Added Django 1.6 to test matrix.
Fixed typo, reenabled complex test app in Tox, although it has no test cases.
Got gis tests passing on postgis.

Reenabled complex tests in py27-dev.
Moved some dependencies away from pip to apt to hopefully speed up installation.
Merge branch 'test-enhancements-more-faster' into test-enhancements
Removed uneeded, commented code.
