[Maposmatic-dev] Public Buildings in index

[malenki]

I realised that a lot of amentiy=* show up in the index of the created
maps as Public Buildings and have only their name on it. This gets
confusing when there is e.g. a post office in a stationery shop without
a descriptive name. 
The result is e.g. an index entry "Stationery and Toys John Doe".
My suggestion: prepend a (translatable) description of the amenity in
front of its name. 
My example would be then: "Post Office: Stationery and Toys John Doe"
