PowerPoint writer: Correct application of reference doc for content
Previously we had applied content shapes based on their index (which was "1", "2" in MS Word 2013). It turns out that this was a convention, and could not be relied on. Instead we use a default type (ie, a ph tag with no "type"). This is more correct, and should make the application of reference documents in PowerPoint much more robust.
