newt: Add new package

From the README:
Newt is a programming library for color text mode, widget based user
interfaces.  Newt can be used to add stacked windows, entry widgets,
checkboxes, radio buttons, labels, plain text fields, scrollbars,
etc., to text mode user interfaces.  Newt is based on the slang library.
