autoopen marker note

[matkoniecz]

some challenges (like http://maproulette.org/map/1454/1404888) have useful info in marker popup.

In that case marker popup contains

name: "Centrum powiadamiania ratunkowe..
note: "emergency=phone is to mark a pl..
phone: "112"
wikidata: "Q510646"
addr:city: "Lublin"
wikipedia: "pl:Centrum powiadamiania r..
addr:street: "Antoniego Szczerbowskiego"
addr:postcode: "20-012"
addr:housenumber: "6"

Currently user must on every task manually click marker to show popup.

It is preferable to show popup automatically.
