What does this pull request do?

Noticed when I captured Aspid that the QM came back 30s after kesu. Applying it to all of them.

Steps to test these changes

After re-reviewing the QMs were already set to the correct timer but the NMs themselves had duplicate logic on a separate timer... so I just removed anything dealing with the QMs from the NM scripts since the QM scripts use the right function to handle showing/hiding the QM.

I renamed Fafnir and Behemoth QMs while I was at it and correctly a wrong !pos in the header for Fafnir.
