From: Peter T Mount <patches@maidast.demon.co.uk>

This patch fixes the following:

* Fixes minor bug found in DatabaseMetaData.getTables() where it doesn't
  handle default table types.
* It now reports an error if the client opens a database using
  properties, and either the user or password properties are missing. This
  should make the recent problem with Servlets easier to find.
* Commented out obsolete property in Driver.getPropertyInfo()
