[Groff] New project: `RUNOFF'

[Bernd Warken]

`RUNOFF' is the predecessor of `roff'.  I started a project `contrib/RUNOFF' 
with documentation.
So far, it only contains 2 man-pages.

The file `runoff.man' has a large `hdtbl' table which looks vary nice in 
graphical `troff'.
As `nroff' isn't supported by `hdtbl', an additional `tbl' had to be generated.

The other man-page `groff_filenames.man' describes the file management since 
`RUNOFF'.

Enjoy
