Bug#949977: ITP: libgnt -- GLib Ncurses Toolkit

[Richard Laager <rlaager@wiktel.com>]

This obviously took me a long time to get to, but I finally have.

1. As discussed with Ari, I have adopted the Pidgin package. I also
   made a few cleanups at the same time. More extensive updating (e.g.
   to modern debhelper compat) will probably have to wait until after
   bullseye, given the impending freeze.
2. I have uploaded libgnt, which should hit the NEW queue.
3. I have a Pidgin 2.14.1 package prepared, which uses the libgnt
   package. As soon as libgnt clears NEW, I can upload pidgin.
