On the system info page (http://localhost:5000/_admin/settings/system) we are displaying the versions of git, mercurial and subversion. Only in the git case we query the VCSServer to tell us uns which version it uses. In the case of mercurial and subversion we are using the packages which are available to RhodeCode if they are available. This is wrong because we want to display the versions which the VCSServer uses and not RhodeCode. We should change this to query the VCSServer for all of them.
