    Simplify dialog for writing our torrc
    
    During the Nyx rewrite I've been making ourself less catering to extremely
    weird situations. One of those is screens that are less that twenty columns
    wide. Silly to have special logic elongating our dialog just for that.
    
    Also, dialog now closes when you press 'esc'.
