Ufopaedia armor text + armor bonuses

Now armors have ufopaedia descriptions (largely "inspired" from TFTD)
Armor bonuses added also (default values 0, may have negative values as penalties also).
Extra ruleset armor nodes: baseTUBonus, percentTUBonus, baseStaminaBonus, percentStaminaBonus, baseStrengthBonus, percentStrengthBonus - not added in ruleset.
Formula is BonusX=(percentXBonus*MaxX)/100+baseXBonus, so that fullX=MaxX+BonusX.
