MINOR Checking for SiteTree class existence in Security, Translatable
MINOR Checking for ContentController existence in FulltextSearchable
MINOR Removed unnecessary ContentController tests from ObjectTest
MINOR Replaced CMS specific examples in PermissionCheckboxSetFieldTest, DataObjectTest
MINOR Changed SecurityTest to make assertions against Security/login rather than relying on redirection from admin/cms
ENHANCEMENT Making $permissionCode argument optional for BasicAuth::requireLogin(). If not set the logic only checks for a valid account (but no group memberships)
ENHANCEMENT Using SS_HTTPResponse_Exception instead of header()/die() in BasicAuth::requireLogin() to make it more testable (from r107867)
