Improve Design and Markup of Submission Page

This PR contains a rewriting of the whole submissions page to make it more compact and see the code in the current viewport. It makes the actions more scalable (introducing a toolbar), replaces iterations with tabs and meaningful icons (check, in progress icon). It is also showing the user some alerts if a submission is hibernating or finished. This should fix #1687.

Afterwards I would be happy to tackling other improvements on the submission page like #2022.
