[stellation-res] Fix for 31915

["Mark C. Chu-Carroll" <mcc@xxxxxxxxxxxxxx>]

I just posted a patch for 31915. This one is non-trivial: it's provides
the implementation for the remote-access versions of the get*Comment
methods. I incorporated tests for it into the AclTestCase in unittest.
It may seem like an odd place to put it; but that unit test does a ton
of repository operations while testing the ACLs, so just checking the
comments while that's going on is very easy, and doesn't add Yet Another
test suite.
