[Tagging] Updating definition and description of place=square

[Tom Pfeifer]

I fully agree with Martin here. The place=* key is used in OSM to indicate that a particular 
location is known by a particular name, and that is independent of details of the usage.

It might be that Joseph's perspective is driven by his intense work on the Carto style,
where it has to be decided if a name is being rendered in the place-style or in the park-style.

However OSM is more than rendering, it is about analysing the data. And when I ask e.g. Nominatim
or Overpass where all the Squares in my town are, I wish them to be included by the place=square tag 
and not lose some where the place tag has been omitted just because they are filled with a park.
