directoies for the htmlized source code at hurd.gnu.org

[Jim Franklin]

Hi folks
 As I'm creating the web pages for hurd.gnu.org I am using a boilerplate
that assumes the source code home directories to be:

/software/hurd/hurd_src/
/software/hurd/gnumach_src/

This should keep it seperated from the other pages and make it easy to
update by script when necessary. If you want to use other directories than
the ones above just let me know and I'll make the appropriate changes in the
boilerplate.

Jim
