After long consideration we came to the conclusion that user
configuration in /etc should always override the (generally
computer generated) configuration in /run. User configuration
should always be what matters over anything else. Hence rearrange
the search orders accordingly. In general this should change
very little as overriding like this is seldomn done so far,
and the order between /etc and /usr stays the same.

+Rules files in /etc/udev/rules.s/ with the same name as rules files in
+/run/udev/rules.d/ now always have precedence. The stack of files is now:
+/usr/lib (package), /run (runtime, auto-generated), /etc (admin), while
+the later ones override the earlier ones. In other words: the admin has
+always the last say.
