Armor rebalancing

Changed the resists of Armor to make them more usefull and balanced.

Leather Armor now gives a Little bit more Armor but no more resists to weapons. Instead it gives a little bit resist to magic and is a Little bit weak to Bows.
Chain Armor is now weak to Thrust. Nerved the given Resists a little bit and taken Aware the Bludgeon resist.
Scale Armor is changed to have most balanced Weapon resists.
Plate Armor is now the strongest Melee armor but very weak to Magic.
Nerudit Armor is now the strongest Anti Magic Armor (but lowered its cold resistance). But also its very weak to Melee weapons now.
