[Tagging] shop=fashion

[Simon Poole]

Working on this issue

https://github.com/simonpoole/beautified-JOSM-preset/issues/27

the question turned up if shop=fashion (with 5000 something uses) 
should not be deprecated (==not offered for new use) due to overlap with
shop=boutique (~11'000 uses) and shop=clothes, clothes=fashion (not
particularly popular with roughly 200 uses). It just doesn't seem to
have a good definition, which is already pointed out on the wiki page
(but without a conclusion).

Any opinions?
