Integrating the VIP Theme Review with the main plugin.

In response to #59. Rolled the VIP Theme Review into the main plugin and
got rid of the standalone plugin for the VIP rules.

Placed the code for creating the fancy form on the VIP Theme Review page
in vip-scanner/config-vip-scanner-wpcom-form.php.
