Railgunner Crit Fix

Standalone from SurvivorsPlus (DO NOT USE WITH SURVIVORSPLUS). Crit damage is additive, a critical hit already does double (200%) damage, adding 10% to that is only a 5% increase overall. This mod doubles the added crit chance so it actually does the correct damage. Applies to all crit items. (yes even laser scope, that did half damage before this)
