Improved checking if the open GUI is ours. Thanks, GodsDead, for the bug report!
Fixed admin bypass permissions not being taken into account when using commands. Thanks, yriokiri and Endaar, for the bug reports!
When moving a powerblock, selecting the current powerblock's location will no longer tell you that the location is already occupied. Instead, it'll just tell you everything went well.
Executing "/listdoors" in the console without any player/doorName argument will now list all doors instead of complain about being unable to find any doors.
Added new notification system for door creators. Thanks, IronAR, for the suggestion! This allows door creators to opt-in on a per-door basis to receive notifications whenever a door is toggled.
Added config option "allowNotifications" (default: true) to enable/disable the notification system.
Added permission node "bigdoors.user.receivenotifications" that gives access to both signing up for and receiving notifications. (again, only the original creator of a door has access to this!)
Added command "/setnotification <doorName || doorUID> <true || false>" to enable/disable notifications for a door. There's also a corresponding GUI option.
Added new localizable messages for the notification system.
