Update document_title_reporter.js

Tidy up, Added a tick and cross-mark (Unicode) to title text to complement icons (also if they don't work locally like in Chrome), also allowed path to the icons to be set via meta tag (before js request) with name 'iconsReporterPath' - fallback to 'helpers/passed.ico'
