Tell gitweb about repo owner via git-config

Gitolite uses projects.list to set the owners for gitweb's use.
Unfortunately, this does not work for gitweb setups that set
$projectroot to a directory, thus generating the list of
repositories on the fly.

This patch changes that: gitolite now writes the gitweb.owner
configuration variable for each repository (and properly cleans up after
itself if the owner is removed).

The patch causes gitolite not to write the owner to projects.list
anymore, as this would be redundant.

The owner also needs no longer be escaped, so this patch removes the
poor man's 's/ /+/g' escaping previously in place.

Note that I am not a Perl coder. Thus there are probably better ways to
implement this, but at least it works.
