Update-Playershops Issue

[Elgrim]

Was going to run this today since FWI appears out of date.

Getting an error when run, and yes, its trusted.

The script was using the Setting class from Lich 4.6. I uploaded it to the new repository when I thought only people on the new version of Lich would have the new repository. Now that that's changed, I've updated the script to check before using it. So, it'll run, but it won't save and reuse data to cut the run time in half unless you're on Lich 4.6.
