Armor of Gort damage cap fix

Armor of Gort wasn't capping damage taken properly, because order
mattered. To receive the full benefit of Armor of Gort, a player would
have to buff while already wearing his armor, and then never switch to
any other item. Switching would lose the benefits due to pushing Armor
of Gort later in the list of defense mods.

This change moves the capping mechanism before all defense modifiers.
