Extra Spell Attributes (RPG Series Tweaks)

Removed those crappy Vulnerability enchants - no more enchant bloat
Replaced them with 1 enchants instead of like 5:

• Guerilla: Chance to go invisible after dealing enough damage in a short amount of time

Vulnerability no longer exists, and is now just Sneak Attack, a skill for the Rogue book, if Rogues and Warriors is installed:

• Sneak Attack:  Strike with a melee attack for 1.5x damage. When you are concealed via Invisibility effect (Invisibility, Vanish, etc...), this melee attack always crits. If it naturally crits on top of that, this attack ignores armor.

Absorbing  now takes into account all damage reduction instead of just from armor. Protection and other enchants matter. This means blocking with a shield or otherwise taking no damage from something recoups the according amount of Absorption. Absorbing values halved to compensate. 

Fixed several bugs related to Recoup mechanics.

Clarified and shortened descriptions and names.
