[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.
