Inconsistent behavior of Windows authentication between IIS integration and WebListener

Both add Negotiate and NTLM.

WebListener gives the schemes display names of Windows:Negotiate and Windows:NTLM.
With IIS integration the display names are empty.

Since display name is often used in generic code to populate the login page - it would be nice to always have a display name - or never. But be consistent ;)

The display names were removed from IISIntegration so it wouldn't show up in the interactive login page, so we should also remove them from WebListener.
