Changes the header for shop_log and start_shop.

1)  Pages will go back to shop_welcome (original behavior) but for these two pages.  This prevents transaction pages from going back.
2) Added an About/Help link to the left.
3) Changed the width/margin of the associated tables so that it would line up withe new table presenting the menu links.
