Document all supported versions in PyPI using trove classifiers.
Alphabetize classifiers.
Add all supported versions to tox.ini for easy testing. Tidy up tox.ini
by removing defaults for basepython.
Add all supported versions to the Travis CI configuration for CI
testing.
Use Tox-Travis to help build the test matrix as the different versions
of Django do not have complete overlap of Python support.
Update Travis configuration to use built in pip caching support.

* Add Django 1.8 to test environments in tox.ini
* Update python versions supported by Django master in tox.ini
* Don't load 'url' from template library 'future' - it is no longer
available in Django master, and is not needed in Django 1.4 and later,
which is as far back as django-constance tests
* get_cache dropped from Django master
* post_syncdb signal dropped
* django.utils.importlib dropped
There are still errors on some environments that I didn't try to
address:
* coverage seems broken on py32
* django-master seems currently broken on py27 (non-ASCII character
somewhere,
I expect django-master will be fixed soon since they still claim py27
support)
* django14 seems broken: "NoReverseMatch: u"'admin" is not a registered
namespace"
