[Tagging] Nicknames

[Daniel Koć]

I think it'd be good to add "Big Apple" nickname as a popular (and 
searchable) kind of placename for a New York:

However nicknames are not defined on the wiki nor used too much as 
"nickname" (just 44 objects):

https://taginfo.openstreetmap.org/keys/nickname


The currently stored names (tags without language codes) are:

alt_name=New York City

name=New York

official_name=City of New York

short_name=NYC


Should we add "nickname" as another standard naming scheme in wiki 
definition?
