- Added Staff Chat (/sc):
Staff Chat has been implemented.
Now, players who are OP and those with the "roleplaybasics.staffchat" permission can chat among themselves.
This chat is separate from the OOC command and encompasses players in all worlds.

- Added Local Chat System:
A new local chat system has been implemented.
You can enable this feature by setting the "local-chat-mode" variable in the config.yml file to "true".
This will turn the default messaging system in the game into local chat mode.

- Added Roleplay Name Integration:
Roleplay name integration has been implemented.
Now, if users' names contain the underscore "_" character, it will be replaced with a space " " to conform to the roleplay name system.
