Registration Details:

• If no argument is provided to registration commands, a menu displaying the players currently in the game is shown.
• The commands accept either the player's name or their SteamID.

SQL Details:

• The database stores the player's SteamID along with the server ID.
• Only players from the assigned server ID are retrieved.
• Players are added to the whitelist.
• A command is available to re-download the player list in case of discrepancies.

Self-Registration:

• Players on the whitelist can self-register as casters.
• Administrators can self-appoint as casters even if they are not on the whitelist.

Convars:

• "caster_whitelist" disables the whitelist, allowing any user to register as a caster.
• "caster_selfreg" enables self-registration commands.
• "caster_addons" enables custom caster addons.
• "caster_kickspecs_inmunity" enables a list of players who are immune to the sm_kickspecs command.

API Enhancements:

• Added hooks and forwards to handle casters, whitelist, and immunity.
