- Added the /mtbp update command. This will allow server administrators to update all backpacks on the server to the size in the config or some other size. This is in order to facilitate updates if something needs to be nerfed. It should be noted that this command does have the potential to lead to item loss, and/or upgrade loss depending on how it's used!

- This update also adds /bp preview <backpack> in the help message, as it was omitted.
