[MIRROR] SM cascade is viable with gas and more visually interesting [MDB IGNORE] (#13723)

* SM cascade is viable with gas and more visually interesting (#67079)

Fixes the check for antinob+hypernob cascade for the total amount of gases from the combined_gas to the environmental one.
Allows more damage to the crystal while the cascade is going
Made the antinob and hypernob heat penalty in similar but opposite amounts (15 anti, -13 hyper)
Added transmit modifiers to both gases (-5 anti, 3 hyper)
Increased the amount of crystal shards that spawns from the explosion to a max of 5 and min 2
Added light breaking and random light on emergency mode + maint emergency access when the cascade occurs

* SM cascade is viable with gas and more visually interesting
