* Armor Sets: Wrong skill Id. (The Note was fine, but the Id was wrong).
	* Skill Trees: Wrong level. (Confirmed at PowerWiki).

	* No more Skill Tree XML files looking like CSV files.
	* Documentation updated.
	* Skill Id and level have been split to avoid useless parsing, and improve readability.
	* Now list of attributes are now placed as sub-elements of the current skill and not in comma-separated attributes.
	* The races are read from its text representation instead of the numeric Id, more user friendly!
	* Social classes are read from its text representation too, more user friendly!
	* All constraints are in the XSD file.
		* They are stricter now.

	* Added gameMasterSkillTree.xml
	* Added gameMasterAuraSkillTree.xml
	* Added heroSkillTree.xml
	* Added nobleSkillTree.xml

This unhardcodes this skill trees and allows easy update/customization.

BETA/STABLE: More stages were added to Fast Recovery skill (2nd Stage: Increase in Recovery bonus at level 49), also fixing Ticket #4974.
