Git (gitolite + git-http-backend + gitweb) configuration

By default repos are be readable by gitweb and the web server ('gitweb' and
'www-data' are both in the 'gitolite' group).  Private repo owners will have
'chmod -R og-rwx' manually.

To automatically add new repos to gitweb's 'project.list' file, make it
readable to the special 'gitweb' user.

See /usr/share/doc/gitolite3/README.txt.gz for details.
