Korma queries don't log passed parameters

I have a patch in progress (zerokarmaleft/blackwater@48a3ff50358ca6ec7409991a658398b9f082451b), but I figured I'd bounce the idea off of you first to see if you had a preference for a different approach. Changing the arity of `log-sql` breaks the jdbc module obviously, but it doesn't look like the jdbc hooks are adding passed parameters to the log output either.

Start by inspecting the `log-sql` entry point and the JDBC hooks mentioned in the issue, then compare the proposed approach in commit 48a3ff50358ca6ec7409991a658398b9f082451b. Done means passed query parameters appear in log output while the JDBC module continues to work.
