Change my Git e-mail to scy.name
Change Rxvt Xresources to URxvt

URxvt accepts Rxvt resources as well, for compatibility with Rxvt.
However, I'm not using Rxvt at all at the moment, and I've never used it
(as far as I can remember). If there ever comes the time when I start
using Rxvt without the U, I can configure it based on these resources.
But not until I have a real Rxvt to see how the settings actually affect
its behavior.
Add my own terminal selection mechanism: scy-term
Make i3 use scy-term

I needed to modify .xinitrc in order to make it set the correct $PATH.
I've implemented my $MASTERPATH method from .sh/environment in order to
have no duplicates in the $PATH.

($MASTERPATH is set in the same way that .sh/environment sets it, so the
two mechanisms don't conflict with each other.)
Start urxvtd in .xinitrc, set RXVT_SOCKET
