Add rendering for amenity=doctors

[CloCkWeRX]

Previously, a few people have been keen on seeing amenity:doctors or similar render:

• http://wiki.openstreetmap.org/wiki/Tag:amenity%3Ddoctors
• http://wiki.openstreetmap.org/wiki/Proposed_features/Doctor
• http://wiki.openstreetmap.org/wiki/Proposed_features/Clinic_(Medical)
• http://wiki.openstreetmap.org/wiki/Proposed_features/GP_Surgery
• https://trac.openstreetmap.org/ticket/2309 (mapnik)
• https://trac.openstreetmap.org/ticket/4272 (mapnik)
• Add icon, rule for Amenity=doctors openstreetmap/mapnik-stylesheets#8
• https://trac.openstreetmap.org/ticket/4741 (potlatch2)
• https://trac.openstreetmap.org/ticket/4599 (potlatch2)

There are renderings for dentists, and renderings for hospitals; arguably seeing a local GP is more relevant to more individuals who may be using OSM; than visiting a dentist.

Failing that, wontfixing this + the other 4 tickets would be worth doing to clean up the number of open requests.

Just found that, and +1... We shouldn't probably go into the detailed specialities, but one small icon or just the name would be good. No idea at which zoom it should start.

We still don't have the icon for this tag. The same with amenity=clinic.

@wlakom - that is why this ticket is open.

The current behavior also get's odd when you have an amenity=doctors with an address, the house-number will be displayed instead of each doctor, in my case leading to duplicated numbers that are rendered.

See #1041 (comment) for a perhaps clearer icon. I would have proposed it already, but there is #1041 and I didn't want to supercede it.

Resolved by #1201.
