Update tests to run in browsers and node.

Updated build process to convert all json in
test/data into a javascript variable so no http requests
are required.

Updated npm test to run testem ci, which will use the
testem.json to configure the tests.
Add .travis.yml
Update tests.

- Update .travis.yml to only run tests on PhantomJS.
- Update test.js to be more scalebale.
Update spec for readability and add tests.
Remove brand specific tests since they'd all be testing the same functionality.
Fix node tests.
Update Category parsing. Adjust tests.

Category property names are now automatically
parsed from "urn:mtvn:playlist_type" to "playlistType".
A few of the categories still have unique conversions,
which are listed in categoryMap.

Tests now test for all parsed categories. Expected results
should contain all of the parsed categories.
Handle all possible null values.
