I've noticed Ogres now supposedly have the Hurl Boulder ability (yay!) but they never use it(boo!).  Why?

I feel the issue is as follows:

Ogres have this line of code in CoreMonsterUnitTypes.xml:

<SelectedAbilityBonusOption>Spell_HurlBoulder</SelectedAbilityBonusOption>

In CoreAbilities.xml, this is the code that actually unlocks that ability:

            <GameModifier>
                <ModType>Unit</ModType>
                <Attribute>UnlockCombatAbility</Attribute>
                <StrVal>HurlBoulder</StrVal>
                <Provides>Launches a boulder for 8 blunt damage (+2 per level)</Provides>
            </GameModifier>

HurlBoulder is a spell that costs 6 mana that the units don't have.

I believe this should be changed to HurlBoulder_Ability, so the Ogres can properly (and happily) lob their rocks at their foes.

Also, the provides in the ogre description is 8 + 2 per level damage, while the ability is 8 + 1 per level damage.  You must choose one or the other!
