MightyScript: Apply Buff does not apply attack modifier

The "Apply Buff" script action does not adjust the attack damage of its target entity.

To replicate:

• Create a blank map in Map Editor.
• Floodfill the map with Dirt.
• Add for Player 1 a Dungeon Core and a level 1 Gnarling.
• Add for Empire an Inhibitor.
• Add a script with trigger "On Start" and action "Apply Buff", setting "Affected Entity" to the Gnarling and "Damage output multiplier" to 10.
• Export and test the map.
• Immediately take possession of the Gnarling and use its Basic Attack on the Inhibitor.

Expected result: The Inhibitor takes 1375 damage.

Actual result: The Inhibitor takes 137.5 damage (the Gnarling's base damage).
