LOK: Implement parts for Writer too.

In Writer, the meaning of 'parts' is a bit different than in Calc or Impress.
In Writer, the parts mean pages, and the document does not give a completely
different view, the cursor just jumps to the given page.

It is up to the client to follow the cursor appropriately to have the desired
effect.
