[GRASS5] 5.7: man pages generated now

[Markus Neteler]

Hi,

I have made the (minimum) changes to generate MAN
pages in GRASS 5.7-CVS.

Currently they are written to
man/man1/

TODO:
Due to the 'fakestart' problems with some of the
modules, the <TITLE> tag is missing in these pages.
In this case the g.html2man script gives an error.
However, the procedure continues.

This should also help for Debian (maybe someone can post
this to the related ML).

Cheers

 Markus
