Move preloading slider images to 'home'
Limit preloading product images only to 'medium'
Merge branch 'master' of https://github.com/volusion-angular-themes/method
bump themeInfo.json to v0.0.18
removed the invalid comment from en.json

* json files cannot have comments
update .travis.yml

* added -v when executing deploy.sh to output verbose logging
modified gruntfile.js to include jshint when running grunt test
* we want it to fail the build in Travis, and Travis only fails the build if grunt test fails. We have grunt build running only during after_success and per the Travis CI docs: http://docs.travis-ci.com/user/build-lifecycle/#Breaking-the-Build it says "Currently, neither the after_success nor after_failure have any influence on the build result. We have plans to change this behaviour."
* ideally if grunt build fails for any reason we'd want Travis CI to say the build is FAILED
