The Large Construct Update II: Electric Boogaloo

At long last.
-The Juggernaut's Shield spell now spawns a cult version of forcefield, with a new sprite and description.
-The new forcefield also emits a weak red light (same as Beepsky's).
-Fixed the Wraith's Phase Shift animation. It used to loop for the whole duration of the spell. (issue #1418 )
-Wraith, Artificer and Juggernaut now have their red lights glow in the dark (like MoMMi eyes)
-A few modifications to the construct HUD sprites
-Parrots making noise when you feed them crackers
