  See Crumbs - Moderately Critical - Cross Site Scripting (XSS) - SA-CONTRIB-2015-082
  In prior versions (7.x-2.x branch), users with the "Administer Crumbs" permission could use the custom breadcrumb separator for XSS attacks.
  The permission was never intended for random users, but is also not explicitly marked as "trusted roles only". Therefore this counts as a vulnerability.
  In the new version of the module, the separator is validated in the form at admin/structure/crumbs/display, *and* sanitized on output, with filter_xss_admin(). The sanitization is for security, the validation is to make it more visible what is allowed and what isn't.
