Map-Only View

[octycs]

Is your feature request related to a problem? Please describe. This is a rather large feature that may be composed of or solve some smaller ones. It could solve #210 and #223

Describe the solution you'd like The idea is to have a map view in the webclient, where you can open a (fullscreen) map (like Google Maps / OSM) without first going to an entry via search.

Describe alternatives you've considered We could do it on a per-campus basis, so that you first go to a campus page and then click on the map, where we add the features, but I don't think this is necessary.

Additional context This is primarily a webclient feature and makes sense to await #200
