logging patch

I've been using fixture_references, and have been getting errors from
my database about incorrect values inserted. fixture_references turns
off logging by using the silence method. The present implementation gives
me no way to turn that back on temporarily without commenting out code.
I'd like to propose the patch below, or something like it.

I have tried to keep it backwards compatible. I've seen no other unit
tests for logging features, so I couldn't see where to put test logfiles.
As a consequence this has no tests, but I have used it live and it seems
to be working correctly. I've also written it in such a way that
boolean parameters may be avoided. Maybe it can be hammered into a
better shape before acceptance?

        Thank you,
