[Plugin: Better WordPress Google XML Sitemaps (with sitemapindex, multi-site and Google News sitemap

When running SSL for the WordPress dashboard, the tabs on the settings page for Better WordPress Google XML Sitemaps have non-SSL links. The offending code seems to be in BWP_FRAMEWORK::build_tabs().

Rather than the current:
$this->form_tabs[$page] = get_option('siteurl') . '/wp-admin/' . $option_script . '?page=' . $pagelink;

It should be:
$this->form_tabs[$page] = admin_url($option_script . '?page=' . $pagelink);

Then it picks up the proper HTTP/HTTPS based on how the user is logged in.
