PackageManager load additional version without App.config

[lechuckcaptain]

It should be possible to configure additional versions without the need to configure the App.config of the main executable (or assembly).

This should already be possible since PackageManager has its instance publicly available i.e.

var additionalVersion = new Hl7Package(...);
PackageManager.Instance.Packages.Add(additionalVersion);
// or
PackageManager.Instance.Packages.Insert(7, additionalVersion);

Actually, this would only be possible if PackageManager was public which currently it isn't.
This is probably one for the future when we tackle adding configuration as code.
