Support for secure pages module / https paths

I am running this module in conjunction with secure pages - https://www.drupal.org/project/securepages . This module redirects defined paths to be served by SSL.

Secure pages settings defines 2 base URLs, one for https pages and one for http pages. The site uses these instead of the $base_url var in settings.php, in fact setting $base_url can lead to redirect loops.

So because I don't have a $base_url configured, I get "Permission restrictions deny you access to this broken link" in the link checker report for URLs that require SSL as per the secure pages config, eg user/xx .

It would be great if link checker could check for the relevant secure pages variables and use those instead of $base_url if appropriate.
