Added configurable chat command "codelock.skin".
This will let you select the skin used for codelocks when placing a door and having it auto-lock.
You will only be allowed to select a codelock skin that you own.
This only applies to players with the "autocodelock.nolockneed" permission when placing a lock with needing one in your inventory. When the plugin consumes a lock from your inventory it uses the skin of that item
Added chat command "/closer" to enable/disable door closers on a specific door (command can be changed in the config)
Added config option "Hide door closers"
