WORLDGUARD-2605 - Reported by MvLeeuw

I would like to change/remove some of the worldguard messages.
I have a PvP server and I use worldguard to disable global building on the world, but this world contains tall grass and flowers, and while PvPing you sometimes break this multiple times and get spammed with messages like: You do not have the permission to do this (or something like that).
It would be nice if we can disable certain messages and/or change them in the config.
I got also a problem with the Region has been updated message, I sell regions and let the player use the /region owner command automatically but they will get the message: Region updated, which is pretty annoying and it would be nice to have this editable too!
