[Tagging] named spots in settlements (toponyms)

[yvecai]

It's unfortunate the wiki definition of place=neighbourhood defintion 
allows 'fluid borders' and 'well-defined legal and administrative 
borders' at the same time.

Having a tag for informally named places would be a good idea, if the 
*informal* nature survives the wiki definition subsequent edits.
Place=locality covers this for the countryside, so I guess this 
tagshould be populated places-only.
