[age restriction] progress 16/n - refresh/reveal/link tests

Age restriction works now with withdraw, melt/refresh/reveal and link,
including tests.

However, there is still a problem with the tests:  The melting operation
"refresh-melt-failing-age" that should fail (because of conflict), but
currently fails for other reasons.  I decided to disable that particular
test (and the next) and submit the patch I have so far.
