Updated PATH in emacs.service putting paths with the form ~/* first so
the binary's located there have higher priority
Added DISPLAY environment variable to the following service files:
+ unclutter
+ xbindkeys
+ xcompmgr
+ xscreensaver
This was an attempt to fix an CURRENTLY UNRESOLVED ISSUE. That is the
above service files don't start when you initially log in. But once X is
loaded can be started successfully by "systemctl --user restart <unit>".
