combust repository change

I've split the combust SVN repository from the perl.org site
repository, because it didn't make any sense to have them in the same
repository.

but, this means everyone needs to execute the following command from
your combust directory.  (i.e. the CBROOT location.)  

rspier@bear ~/projects/newweb$ svn switch --relocate \
http://svn.perl.org/perl.org/backend/trunk/  \
http://svn.perl.org/combust/backend/trunk/ .

If you don't do this, you won't be able to update combust.
