Subject: [PATCH] Only fetch MAD manifesto on server join (#751)

Previously, the verified mods manifesto was fetched on game start without checking if the verified mod feature is enabled Squirrel-side; with this, the manifesto is only fetched when the user wants to download a mod (meaning they enabled the feature beforehand).
