Title: Allow creation of MvxViewModelLoader to be overridden.

I think this approach is cleaner than to override InitializeViewModelFramework and re-register a new ViewModelLoader. Please note: In the new code, a singleton is registered while in the old code, a new instance of MvxViewModelLoader would be created on each load. I figured out this was safe since the standard MvxViewModelLoader does not carry any state (except for the LocatorCollection, and that shouldn't change in a typocal app I guess).
