Travis config file

[tomelm]

This adds Travis CI configs for testing

The test suite is running on CI now, but there are some test failures. I looked through the traceback but since I don't have a complete understanding of what's going on I can't really diagnose if this is a config failure.

It looks like all of the failures are similar:

@ivanlei or anyone else, can you check? The build is also if you want to see the entire output: https://travis-ci.org/Yelp/osxcollector/builds/45476244

I'm guessing this is what happens when tests are run without a valid config file. Tests shouldn't need a config file. This seems like a bug.

[tomelm]

This should also fix #43 now

This is so awesome. @tomelm you rule!
