[Groff] groff_lilypond v0.2

[Bernd Warken]

In groff_lilypond there are now 2 modes for generating the EPS
files:
  --ly2eps (the new default) and
  --pdf2eps (that's the old mode from version v0.1 with pdf to ps to eps).

With ly2eps mode, lilypond generates the EPS files itself, for each page
one EPS file.

Unfortunately the .PSPIC works only in groff pdf and dvi mode, not in ps.
Tty, X and html mode have errors and display only a rectangle with the
file name.

To fix that is beyond my knowledge.

I could write the groff_lilypond program only by the knowledge that many
of you gave per email.  I thank you very much.
