options: accept 'set minicolor' for setting the color of the minibar

When it is not specified, it defaults to the value for 'titlecolor'.

When not using --minibar, I want the title bar to be blue (as that is
how I've always had it), but with --minibar, I want this mini bar to
be grey, as otherwise it reminds me too much of the prompt bar.

Also, colorize 'set minicolor' as valid in a nanorc file.
