Resolve "Click on map image of room to show TA where you are"

What does this mr do?

Whenever there is a map attached to a room when enqueueing, the student has to select a position on the map. When the TA opens the request it will show in the request what position the student has selected on the map.

Needs !253 (merged), because of rebase.
