Create admin user in episerver after creating new site

If you ever create a new Episerver site with a default membership provider and cannot login since you don't have any current user account in the membership database, use the SQL script below to create a user (tempadmin/tempadmin) that belongs to the WebEditors and WebAdmin groups.

Disclaimer:
The created user will have it's password in clear text in the database so after creating this user, be sure to create a real admin user and delete this one.
