Quest: type of crossing

[krzyk]

The basic idea is to look for nodes with highway=crossing and !crossing and ask the user to select what kind of crossing it is (https://wiki.openstreetmap.org/wiki/Key:crossing):

• crossing=traffic_signals
• crossing=uncontrolled
• crossing=island
• crossing=unmarked

Optionally we could also try to handle lack of possibility to cross the street, this would require removal of highway=crossing and adding crossing=no.

Does the OSM specification allow multiple crossing types? If so, then in order to avoid false positives, this quest should.

I think this is fixed by #397. I opened a new issue for the missing traffic island: #495.
