Corrected a bug that prevented normal players from using commands if Permissions was not present.
Player names are no longer case sensitive in commands.
An admin job change now notifies the target player of the change.
New command "/job admin exempt <player>" will toggle exempt status on target <player> and disable job limitations on them until the command is run again.
Exempt is no longer a permission node. See above.
New usage options. Enter "NOTHING" under a usage node (such as "can-use" or "can-break") to remove ALL usages from that category for that job. Enter "ALL" to allow usage of everything for that category.
