Title: Draft of explicit object schema versioning

@cshenry @pfrybar

Explicit versioning on objects. Todo:
- Update Definitions.pm to contain version numbers
- Update ObjectBuilder to produce __version__ function, $VERSION
- Update MS objects to have __upgrade__ function if they need it.

Thoughts?
