Client-side checksum validation of the server

[KjetilIN]

What?

As a client, you still have little control. But if you would be able to validate that the server is using the newest version.
An idea to improve this:

• Add option in config to validate the checksum of the server
• Use the github repos newest version to checksum validate that the server that i am connecting to is the newest version of this repo.

The option is already added, but the checksum logic is not created (src/client/main.rs):

// Check if we are asked to validate the server checksum
    if client_config.get_validate_server() {
        // TODO: implement checksum validation of server repo
        if let Ok(mut ui) = terminal_ui.lock() {
            ui.add_message(format!(
                "{} Validating server repo not implemented!",
                *WARNING_LOG
            ));
        }
    }
