Responsive-Dashboard build script should copy output into parent repository

At the moment the Responsive-Dashboard project builds its CSS / fonts / JS / etc. in the `Responsive-Dashboard/dist` folder. For the sake of simplicity it would be nice to have it put these files in the parent repository so that we can commit them separately. This PR copies the `dist` folder to `../Styles`. This will end up in `project/WebDasboard/Styles`.
