Improve YAML based source control feature

The YAML based ODP looks absolutely promising, but currently feels like a step backwards because it contains less readable information. That makes it impossible to do code reviews or check what changes others have made.

Most of the 'text-based' contents in the NSF seem to be exported already fine to the YAML files (Java, XPages, custom controls, themes, faces-config, etc). But for us to consider using the YAML format we also need a readable export of:

• View column details & column headers: at least the information that's available in the current XML based format

• Source code for Java agents

From what I heard the YAML based ODP syncing is a lot faster, so it would be great if we could have auto import/export to that as well (it seems like that isn't working currently, or am I wrong?)
