Fixed problems with generating the new revision resource. Now we

create a file that only contains the revision number and use the
AddFileDataResource rule for adding it as a resource. We also
handle the case that "svn info" fails (e.g. for source trees not
containing svn information anymore), setting the resource to
"unknown".
