[WIP] Update frontpage to be all search

This prq changes the front page to have all compendiums on them. The searchbar filters the elements shown.
This prq has extraced the allsearch to a single new app, and uses that for the frontpage. I later want to make a bigger prq that extracts the article to a single app, and the editor to another single app.

This fixes #87 .

Still to do (but I'm in Germany till the 4th):
- [ ] Submit the form when selected
- [ ] Go thru the remaining elements (this might be challenging...might)
