NEW ~ The Build Flag
Build permission is now checked on place/break events.
Only checks the highest priority region for build permission (inheriting from parents)
Can be set to allow or deny and takes the -g group switch.
Allow specifically allows the specified group and denies all others.
Deny specifically denies the specified group and allows all others.
Default behavior is to deny nonmembers and allow owners and members.
