Allow muting sale notifications from Faustus

Occasionally, you get spammed with notifications and they cover a third of your screen. This can be especially bad if it happens while in a boss fight or other tense situation. It can even be a problem while just doing stuff in your character inventory which gets covered. Losing a third of your screen to notifications is not good.

Ideally, add an option either to Faustus or to Options>Notifications to allow turning these notifications off entirely.

They will probably add this, I can't remember when Kingsmarch came out of they had the "hide the notifications" option or not in the beginning.
