launch-handler in particular can be coerced into opening things like news: just by
creating a new config file as ENVARC:launch-handler/URL/NEWS.LH
svn path=/trunk/netsurf/; revision=10106
even if URL: is dismounted while NetSurf is running.
Installation adds the lines to configure launch-handler to open URLs in NetSurf.
svn path=/trunk/netsurf/; revision=9835
Doesn't quite work properly because it never calls the callback :)
Probably also gets into an infinite loop if "send mailto: URLs to email application"
is not ticked in OpenURL Prefs.
