[Tagging] Reviewing the use of addr:housename

[Andrew Hain]

The uses of the tag addr:housename in the database[1] does not match
documentation[2] well. A high prroportion of uses are accidental; there were
some bug reports[3][4] against iD, which used to have a housename box at the
beginning of every point for entering addresses, pointing out doubtful use
by new mappers. The top 100 values of the tag tell their own story.
