Florian 478ef3bce7 front-end code refactoring
Since the front-end received much more code (features) than first expected, the files became much too large. For this reason, the JS and CSS code has now been split by component and thus into several small files. However, since there are now many small files, a JS and CSS bundle tool had to come :D.
