This patch rephrases the aura descriptions of hero auras to an uniform standard, to ensure descriptions follow the actual modifications: [player] [class] [change] [attributes], e.g. "Spearmen +1.0 capture attack strength and +25% melee attack damage." instead of "+25% attack and +1 capture for spear soldiers."

The `formation` and `garrison` type aura descriptions are ugly; improvement suggestions are welcome.
