Ernst create point template and controller

Part of RFC #36, following #38.

### Situation
ActivePoint combines all data of a click on the map.

### Problem
This object is reset after every click and should be rendered by a seperate template. Therefore the code should be migrated to a seperate controller that is attached to the template

TODO:
- [ ] Create activePoint template
- [ ] Set box type to activePoint on click on map
- [ ] Create activePoint controller
- [ ] Migrate relavant markup that lives in the other templates to activePoint template
