Bug#1090896: Please include labwc's NEWS.md file

[Juliusz Chroboczek]

Package: labwc
Version: 0.7.4-1

     $ ls /usr/share/doc/labwc/NEWS*
     ls: cannot access '/usr/share/doc/labwc/NEWS*': No such file or directory

Labwc includes a very legible "NEWS.ms" file in its source code, please
include it in the Debian package.
