Bug fix: render tests were never getting run.
Require all app files in unit_test_cov so we can see all coverage %
Fix assertRendersHtml so it runs in the browser too
Fix test runner by adding jquery back in.
After ansible sets up simple file-sharing webserver on port 3000, rake sauce_test will rsync files to it and run tests on Sauce.
Not using Sauce Connect anymore, so don't ignore log.
