Toggleable Commands via commands.yml
Added a new commands.yml file that allows users to enable or disable specific commands.

New Placeholders Added:
%FateHub_first_joined_short% → Returns first join date in MM/DD/YYYY format.
%FateHub_first_joined_short_universal% → Returns first join date in DD/MM/YYYY format.
%FateHub_join_count% → Displays the number of times a player has joined the server

Fixed several other things while removing old code and updating APIs.
