Check_MK Werk 2651: Do not allow adding of duplicate hosts anymore

ID: 2651 Title: Do not allow adding of duplicate hosts anymore Component: WATO Level: 1 Class: New Feature Version: 1.2.7i3 WATO now makes sure that you cannot add a host with a name that already exists in some folder anymore. That avoids problems when later activating changes (where duplicate hosts are not allowed anyway). Note: In previous versions you <i>could</i> have created a host with the same name on different sites. This is not possible anymore.
