Minor bug fixes.
- Fixed Hologram config entries not fully deleting causing other holograms not to load.
- Fixed Hologram loader to not stop loading holograms if a single hologram failed to load.
- Fixed Hologram command not tab completing the stat types.
- Added another safety check if hologram is null to not attempt to update the board.
- Fixed debug mode override by the config.
- Updated some of the default hologram related messages in the messages.yml (This will only affect newly generated configs.)
