Add banner stretched across header

Try this, it will also help you understand some basic CSS if you're new to that as well!
Edit: Take out the <td> and table-related codes, a good rule of thumb is to always use <div> class or style whenever possible in vB4. The table codes are older and only used when applicable per case-use or situation. Div classes and inline style are more modern for vB4, you can also pull off the same if not better appearance using div classes with CSS definitions.
