more work on the support for multiple inventory servers.

The Login service should now read/create new inventory on the inventory server that is set in a users profile.
Also added "Add-InventoryHost" console command to add a support for a new server to a region.
So it would be good if someone could test this. Set up the grid as normal, but then also run extra inventory server on a different computer (well actually it just has to be on a different network hostname, so one using "http://localhost:8004" and one using "http://127.0.0.1:8005" should work) then you need to manually edit the user profile database to set the new servers url in a user's "userInventoryURI" field. 
Then on a region server, use the Add-InventoryHost to add the new server url (always include the full url, including http, but don't add a final /)
Login with that account and see if the inventory works.
Of course these needs to be made more user friendly.
