Bumped Version Number, Better Multisite Support

Removed injected styles to remove wpadmin bar fully
Moved up admin redirect to a faster hook and is_admin check
Added checking if a "Guest" account already exists on another site and adds the existing user to the current demo site automatically and assigns the roles as needed
Made the "wp-blog-header.php" require crawl up a few directories looking for it first. Hopefully this will make it work across more different wordpress configurations.
