When Kraid dies, this code sets the room scroll data so that the camera isn't locked to the bottom left screen of the room. It also spawns the PLM that deletes the ceiling tiles.
In vanilla, when you quick kill Kraid, these two things don't properly happen. This code fixes that.

Overwrites unused foot hitboxes, meaning it uses no freespace. Unless you're doing heavy Kraid edits, you shouldn't need to repoint this.

Original code by PHOSPHOTiDYL, but it also did some weird things like removing Kraid's BG and editing the screen shake effects for some reason. Modified by Nodever2 on 12-21-19 to get rid of those other changes, make the hijack points better so that the scrolls are fixed sooner, and spawn the PLM which deletes the ceiling tiles. I think. It's been a while. Anyway, the original PHOSPHOTiDYL version is still available on the forums if those other changes sound interesting to you.
