[New Feature] Critical Hit-based Death Weapons

[nucspl]

Description:

With critical hits being in Phobos now, this would be nice to see as well. How the death weapon would be triggered will depend on whether or not the "killing shot" does a crit. This opens up potential to do things like flamethrowers exploding occasionally when killed by basic infantry, or every time when killed by snipers.

Or alternatively, instead of requiring a "killing shot", the unit could be made to die from any critical shot, thus triggering the death weapon immediately.

Possible Implementation:

[SOMETECHNO]
Crit.InstantDeath=yes ; boolean, kills the unit from any critical hit, triggering Crit.DeathWeapon immediately
Explodes=yes ; boolean
Crit.DeathWeapon=[weapon] ; needs Explodes=yes to fire
