Fake structures use 'DamageThreshold' under 'Explodes'.

This change means that fake structures take damage at the same
rate as their real counterparts, but explode at 90% of their
max health.

MSLF and PDOF have been given a health buff as only one fake
version of each can be built.

Also fixed mission Monster Tank Madness. Actor v19.Husk required
HealthInfo.
