Server Shader Gate & Enforcer

Added

- shader_hash parameter to the client mod, server mod, and plugin configurations. - The client mod can now automatically calculate the shader file hash using the SHA-256 algorithm. - The hash must be manually specified in the server mod and plugin configurations (required for verification). - A hidden clientVersion parameter in the client mod, server mod, and plugin configurations. - This parameter is not written to the config file and cannot be modified by users or administrators. - The server mod/plugins check clientVersion against their own required version. If a mismatch is detected, the player is kicked with a specific message prompting them to update the client mod. - exempt_players parameter for server mod and plugin configurations. - Allows excluding certain players from configuration and client mod checks. - Exempted players can play on the server without installing the SSGE client mod or using any shaders. - Useful for administrators, moderators, and other server staff. - Server command /ssge reload. - Allows reloading the plugin or server mod configuration without restarting the server. - New connection termination messages and tweaks to existing ones. - On version mismatch: a distinct SSGE client version mismatch message with the required version highlighted in green and a download link. - On shader/config mismatch: a message with the link highlighted in yellow, accompanied by a dark gray warning beneath it. - On client mod absence: a message specifying the required mod version and a download link.

Changed

- Slightly modified the behavior for receiving and writing the link to the ssge_link.txt file. - The link is now sent to the client mod only if there is a configuration mismatch between the client and server. - The client mod now automatically opens the ssge_link.txt file after receiving and writing the link. - The ssge_link.txt file now includes an explanation for its generation, brief shader installation instructions, and a detailed warning about the risks of following external links.
