Subject: [PATCH] EclipseState stores copy of Deck's UnitSystem

With the introduction of Parser::parse methods and the relaxed lifetime
requirement of Deck (i.e. users no longer need to keep a Deck instance
around for EclipseState to be considered valid), the UnitSystem cannot
be a reference, but must rather be stored.

Since the unit system is immutable once the deck is read this is
unproblematic. It's also small and cheap to copy.
