Feature request: Only allow building/destroying outside of Nation Plots with a permission node.

[InsanibleLector]

Description:

Players can build/destroy outside of Nation plots when there is no need to do so. Let us add a feature to the towns config to toggle building/destroying outside of nation plots. This can be overridden on a group/player basis with a permission node.

With this, any areas we need players to build/destroy in outside of a nation plot can be claimed with a nation plot, avoiding the continued issues with world guard type plugins we've run into.
