Add front-end tests

[txels]

I've been willing to get some front-end testing in for a while. This adds the first JS unit tests and the karma test runner is executed as part of the tox build. As a bonus I've also added jshint to the build.

When I run the tests using tox I get 3 errors and 2 failures in the python tests.

Am I doing something wrong?

This is the output I get from tox after I make the above changes:

Any idea how to remove the jshint/karma warnings?

Nice to see Travis reporting green builds, cheers!

I think this can be merged.

I'll merge once travis confirms life is good
