Rebalanced some rigs + SM typo fix

Cause Engineers needs to die faster.

Normal hardsuits + atmos now have 30 melee resistance instead of 40 and
bomb reduced to 20 from 35

CE hardsuit remains at 40 melee, but has bomb reduced to 25

Sec hardsuits melee lowered from 50 to 40 but gets a boost to energy
from 5 to 15
