Implemented version of the student-page using vuetify and the new general layout. The side navigation should be displaying links to the (not yet implemented) detail views of the submissions to provide easy way to change between submission views.

Added BaseLayout component that will serve as bas for the layout of the app. It is modeled after https://next.vuetifyjs.com/examples/layouts/google-contacts . The gradySpeak has been moved to the front-end.
