Option to make it so you must be trusted to use worldedit

[DoogiePC]

PlotSquared Feature Suggestion:
Old plotsquared behaviour made it so added players could NOT use worldedit on someones plot. To use worldedit they had to be trusted. I wish for it to be an option to enable or just default behaviour again.

How should it be implemented?
To limit griefs where possible.
