Twig features

Editing twig templates requires us to set $settings in settings.php. If it were possible I would love to be able to rebuild twig templates from a menu item akin to clearing the caches.

Specifically I am talking about these:

# $settings['twig_auto_reload'] = TRUE;
# $settings['twig_cache'] = FALSE;

This would be a pretty big win for themers - these days most of the time we do not do a lot of templates changes, at times yes, but most its just a small change here and there such as adding a region. Personally I dislike global type settings such as clearing the theme registry on every page load, I just want things like this happen when I need them to.

I don't know if this is actually possible, but if it were that would be grand.
