Observable

[familyfriendlymikey]

Some questions before merging:

• The previous document on observable mentioned imba.when, is that necessary to document?
• What does @ref do?
• Are there plans to have @autorun in classes call imba.commit automatically?
• @observable doesn't seem to work on objects or class instances, is this intended?
• What is automatic disposal?
