First cut of ADODB backend.  I've only tested this on MySql.  I still have some work to do on error handling etc, but it seems to work fine for me.  If you want to try it out, use 'dbtype' => 'ADODB' in index.php

Please let me have any comments.  If you can do any benchmarks, that would be great.

It doesn't suffer from the backslash bug!
