Changes for Theme Developers

• Improve loader performance and logic #1476 #1489 #1491 (thanks @heino). This introduces potential changes if you were loading templates in a non-standard way and with multiple sources (ex: from a theme and plugin directory). Non-existing templates are no longer passed all the way to Twig’s render(), which currently generates an exception.
