adding list of places

I have added a small panel that shows the list of places on the current map.

Clicking on the name shows a popup (even on clusters).

Small problems:
- it loads all the places, no matter how big or small the zoom is. Currently it's not a problem even when unzooming on max, it can become problem later.
- because of how clusters (and popups) are made, if you click on name in the list, that name is in a cluster, and then zoom in, the popup disappears (because it is bound to the "bigger" cluster)

Bigger problem:
- I am too lazy to do proper localization. English is good enough :)
