Ernst create point template and controller

Part of RFC #36, following #38. Comes with: https://github.com/nens/lizard-nxt/pull/227

### 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:
- [x] Create activePoint template
- [x] Set box type to activePoint on click on map
- [x] Create activePoint controller
- [x] Migrate relavant markup that lives in the other templates to activePoint template
@d-weeteling volgens mij heeft dit te maken, met de regen in de tijdbalk. Die is nu nog wel ook als 'tool' beschikbaar'. Dit gaat verder niet over een punt die geklikt is..
