inherent bonuses on metals/woods/leathers

[Penny]

To bring back the unused metals etc.

The idea is that each metal would give a small bonus to an attribute, like gold gives
luck bonus on crafted armor/weapon. For example, bronze gives a small bonus to stamina,
verite to LRC etc.

These are the attributes I should be able to implement (from AOS.cs):

1. RegenHits
   RegenStam
   RegenMana
   DefendChance
   AttackChance
   BonusStr
   BonusDex
   BonusInt
   BonusHits
   BonusStam
   BonusMana
   WeaponDamage
   WeaponSpeed
   SpellDamage
   CastRecovery
   CastSpeed
   LowerManaCost
   LowerRegCost
   ReflectPhysical
   EnhancePotions
   Luck
   SpellChanneling

Just need a thumbs up from Coli The attributes and their value will be easy to add once the other stuff
is taken care of.
