New patch to open "forward" form in ctools modal dialog

Hello,

I tweaked the "forward" module to do the following when the block is configured to render as a link:

1. Check to see if ctools exists and is enabled
2. If so, cause the link to open a ctools modal dialog instead of jump to the forward form page

Also, I discovered that the page title was not getting rendered properly for a panels page that I forwarded to myself. So... I added some logic to the forward_form_submit handler that will optionally override the default page title with a "title" query string parameter if specified.
