Add some more values to beauty=* (#427)

* Add some more values to beauty=*

Added some frequent non-ambigous values from [taginfo](https://taginfo.openstreetmap.org/keys/?key=beauty#values) and [wiki](https://wiki.openstreetmap.org/wiki/Key:beauty).

* improve titles, add waxing, hair->hair_removal

see https://wiki.openstreetmap.org/wiki/Key%3Abeauty:

* use descriptions from wiki
* waxing has similar number of uses as the other new values (see https://taginfo.openstreetmap.org/keys/beauty#values)
* the value "hair" is not documented on wiki (probably because of the overlap with shop=hairdresser)

* better description for "beauty=spa"
