BUG11242: Fix for adding 2 VPN Hosts/network with same name
If one has an IPSec network named "aaa" and an OpenVPn Host with the same name
it was not possible to group them together because of the same name.
Now the Network type is also checked wich allows Entries with same name, but different networks.
