This is a simple fix for 2 types of responses for the Halloween magic spells OVERHEAL / SELF HEAL and SWARM OF BATS / MERASMUS ZAP.

When casting the SWARM OF BATS spell, the player says "deus invictus" (latin for "invincible god"). This was clearly intended for the OVERHEAL spell. The fact that the file name of the responses for SWARM OF BATS is "_sf13_spell_uber01.mp3" confirms this.

The fix simply changes the names of the casted spells in scripts/talker/events.txt, renaming "MerasmusZap" (SWARM OF BATS) to "SelfHeal" (OVERHEAL) and viceversa.
