Release 1.0.1

* Added a frontend unit test boilerplate based on [Karma](http://karma-runner.github.io/) and [Jasmine](http://jasmine.github.io/).
* Added an `useSingleFileBuild` option for the r.js optimizer task.
* Moved the javascript sources into the `Public/` folder to prevent errors from the default apache config of TYPO3.
* Removed the bower dependency and moved to npm as the only package manager for frontend-/dev-dependencies.
* All arguments of the custom Sass `@mixin`s and `@function`s are now validated.
* Some styleguide modifier comments are generated by Sass (f.e. for all `.brandColor` classes).
