While I was on it, I decided to add logging support.

Note that the implementation follows the spec closely, so a test runner
returned by (test-runner-simple) doesn't do logging by default (and
doesn't use its "aux value" field), contrary to the upstream
implementation which doesn't follow the specification so closely.

Logging is enabled on a simple test runner by setting a log file name
via 'test-runner-log-file!' (a non-standard extension).  This is done
automatically when using 'test-begin' (or 'test-group') without first
installing a test runner explicitly, thus the behavior is the same as
upstream SRFI-64 in the most usual case, without needing the user to use
the non-standard extension.

This was the only thing upstream SRFI-64 was capable of which this
implementation wasn't, so I believe this implementation is now very
strictly an improvement over the upstream one.
