Show distance to an arbitrary point

[M4rtinK]

Make it easy to show distance from an arbitrary point to the current position.

The point detail page looks like a an ideal place for it, with possibly an option to also show it on the long-press pop-up as well.

It is VERY useful to see the distance to your destination point "as crow flies" on the main map screen, when you are on a pleasure or trekking trip and there are no roads for routing (e.g. dense forests, steppes, seas and lakes). I would suggest the following scenario:

1. select a POI / tap a point on the map
2. in the long-press pop-up choose "Point bearing" (or whatever it is called)
3. get a constantly present arrow pointing in the direction of the chosen point and the distance besides the current location pointer and the chosen point.
4. the same menu should show the opposite option "hide point bearing".

This will help to know whether you are approaching the point or not and if your direction of movement deviates from the straight way towards it.
