Feature Request - Ability to customize no access message

[kaanakduman]

Hi, could you please add the ability to customize https://github.com/Multiverse/Multiverse-Core/blob/4bdeacfd0516a7eed2c2c591861ab5b9c945876e/src/main/java/com/onarandombox/MultiverseCore/utils/PermissionTools.java#L234. As a server owner, I would like to explain why they don't have permission to go there and how they can get permission.

Just use a plugin such as MessageFilter to change the message, works fine.
