Simplify tripflags: remove tripflag_names[]

This removes the tripflag name array, since it's not actually useful.
The only information we ever save in the XML file is whether a dive is
explicitly not supposed to ever be grouped with a trip ("NOTRIP"), and
everything else is implicit.

I'm going to simplify the trip flags further (possibly removing it
entirely - like I did for dive trips already), and don't like having to
maintain the tripflag_names[] array logic.
