Multi-db v3.0.3 beta

Hi gang
I've attached a zip of the db.php for testing before I upload it as version 3.0.3 of the multi-db plugin.

This version should enforce the collation and charset across all databases and fix the "strange character" errors that have been reported for version 3.0.2.

It would be great, if you previously had that issue, if you could download and try this version and let me know if it solves the problem.

As with previous versions, the db-config.php file isn't included in this zip and shouldn't need changing.
