What does this pull request do?

• Removes the elemental randomization from Tonberrys Elemental in Jungle Boogeymen (For now) until handling of SMN pets is corrected. Set them to a spell list with Water/Light/Fire Elemental and set the default to Light Elemental.

• Corrects some over-aggressive cast times to the intended time. (Every 20 seconds)

recast = random(MAGIC_COOL / 2, MAGIC_COOL)

Steps to test these changes

Run Jungle Boogeymen, Under Observation, Carapace Combatants or The Worms Turn
