Implemented py.test runner in setup.py

Other highlights:

• Switched to travis build matrix from tox
• Removed runtest.py blob
• Updated tox.ini to reflect documented version compatibility

Suggestions:

• Remove Python 3.2 and Django 1.7 since both are EOL
• Add coverage reporting

@scottfisk what do you think of these changes? I'm happy with merging them if you are.

[scottfisk]

@georgemarshall It looks like python 3.2 wasn't in the environments before here or travis.yml Since one of your suggestions was to remove it, we can probably just leave it out?

We should probably remove any other references to python 3.2 while we are at it.

[georgemarshall]

Ha, you're right... Must of stayed up later than I should have.

@georgemarshall I do like the coverage reporting as well 👍

@jerel Dropped one comment in re python 3.2

[georgemarshall]

Any feedback on Django 1.7 EOL?

[scottfisk]

@georgemarshall I was the only one using it last time we did a poll. We am now using 1.9, so I am ok with dropping it.
