Death variables and the result of not appending _DEAD to them

Problem: Dead("[NAME]") triggers don't work because the check for them doesn't respect how they have _DEAD appended to them in the original game

Reproduce it:

A: Walk north to the exit portal. Nordom will speak, but the check to open the portal will not work

B: Kill the wererat in the basement. You won't ever be able to tell Phineas about it.

Clickable infopoints, and the endless variety of uses for them

Problem: All these saves demonstrate critical clickable points that should start dialog with you. This is a tiny selection.
