Bug#574131: xdg-utils: xdg-email never launchs a mua if desktop is not gnome neither kde neither xfce

[Per Olofsson]

Hi again,

I've applied two patches to the git repo now to add support for $MAILER
and fallback to mutt. They're attached.

I've attached them; please take a look at them. Thank you for your help!
