Code block bugs and Rogue Hub on scripts page

@tempegoreng, You were right. The feature works, but it wasn't set to accept Python; Although the editor option list made it seem so. I've just now added support for it. I've also added support for Rust.

import random
import string

def generate_password(length=12):
    characters = string.ascii_letters + string.digits + string.punctuation
    password = ''.join(random.choice(characters) for i in range(length))
    return password

// This is the main function.
fn main() {
    // Statements here are executed when the compiled binary is called.

    // Print text to the console.
    println!("Hello World!");
}
