CoP 6-4: One to Be Feared Fixes

This commit addresses the following issues:

1) Broken Airship Door due to outdated NPC ID (blocker in progressing in the battle)

2) Fixed clunky teleporting between phases of the fight - rewrote the teleporting to be less hacky and happen after the event between fights finishes. This makes it appear proper to the player.

3) Added healing between phases. Players are supposed to get the HP & MP restored in between phases of the fight, but their TP set to 0
