Must stripslash input fields for db install

[johanee]

During WordPress database install we must stripslash the input fields.

For database name, database username and database password \, ', and " are valid characters. For dbhost "strange" characters probably aren't valid, but we should handle it correctly anyway.

For prefix there is no need to stripslash as we immediately make sure it only contains letters, numbers and underscores. (mysql allows other characters, but it is probably wise to limit it anyway).

Please wait.

Obviously we must then addslashes() when saving to wp-config.php. Updating and actually testing patch!
