Added an option to provide a Discord webhook URL to make images generated in-game copied to a Discord channel. This can be helpful for moderation purposes.

Added the drmap.place.magic permission which allows players to quick-place the rest of the item frames from the same image. This will respect GriefPrevention claims and Worldguard regions but may not respect other protection plugins.

Added an update checker so you can be notified when there's an update.
