[IronPython] hosting and SetVariable

[Dino Viehland]

ScriptRuntime.LoadAssembly is the equivalent.  The only difference is there's no string overload so you need to pass it the actual Assembly object yourself which gives you control over how it gets loaded.

Ok, one more question and I should be good to go. I used to call
Microsoft.Scripting.ClrModule.GetInstance().AddReference to add
references from my hosting code. With the latest beta, I don't see
that anywhere and was wondering how to do this.

thanks
