today's Qt status update: non-standard conditions

Qt's status highlighting was treating any change to hunger or
to encumbrance as "worse" (shown in red).  That's wrong if you
go from weak to just hungry or from stressed to encumbered.

Comparing satiated with other hunger states is tricky.  I've
ranked it between hungry and weak but that's fairly arbitrary.

Also, change the highlighting when Lev, Fly, and Ride are new
conditions from red to blue.
