Solve 'The Darksaber' Problem

[dicewrench]

Sabine and SC Maul both have an Upgrade called 'The Darksaber'. But the card has different art and rules. There are separate Armament entries for both, with requirements for the correct Units.

HOWEVER, when spawning the army you'll always get Sabine's Darksaber back because it is first in the array. So we need to check requirements if there are any.... or agree to special naming these and letting the list builders know the plan.
