…he admin page

Changes:
- use User.query() in admin.controller instead of $http

…ing uibootstrap

Changes: (only if ui-bootstrap is selected)
- add `client/components/modal` folder
- modal folder contains service, markup template, and stylesheet
- modal service is intended to be extended, comes with `Modal.confirm.delete()` method
- admin and main page will both use `Modal.confirm.delete()`

Todo:
- review code for cleanliness and correctness
- possibly extend the modal service to include a basic alert class?
- write test for `Modal` service?

Changes:
- Update jshint task in `Gruntfile.js` to include `serverTest`
- Add `server/.jshintrc-spec` that extends `server/.jshintrc` with spec globals
- Use `"latedef": "nofunc"` instead of `"latedef": true` in `server/.jshintrc`
- Add assertion for `jshint` task in generator tests for `defaultOptions`
- Fix pre exsisting lint errors in `server` and `client`
- Change `getEmail()` in `client/app/account/settings/settings.controller` to use `user` arg and not `$scope.user`
