WORLDGUARD-2544 - Reported by Vikestart

Hello. Great work at World Guard, love it, just want to come with a suggestion for a new feature.

It would be great if you could add the option to disallow tree-spawning across regions.

For example, I have a town setup with World Guard, and I want to prevent inhabitants from having their trees spawned at the edge of their plot cross over into the town's region.
