Fix CI Shims and Specs

Due to a misunderstanding in how browserify processes files, right now the CI shims are always being included in the build. We shouldn't be including these shims in any build that gets executed in a real browser. Instead of adding the shims to the app at bootstrap the index file should conditionally include a ci-shims.js file created in the concat gulp task.

Also the login/register functionality has been removed so the specs need to be disabled or removed.

### Acceptance Criteria
1. CI builds include ci-shims.js in the index file head
1. `gulp disyntegrate:ci` works as before
1. Login/Register specs don't run anymore

### Additional Notes
- `gulp build` creates a ci-shims file that includes es5 shims and the click shim
- `--env ci` includes ci-shims.js in the index.html file head section
