annotations in the 'document tie file'. Every attribute of kpdf dss
can be dumped to disk. Only rendering prevents HEAD merging now! :-)

Annotations:
  Storage: full annotations saving/loding on the tied XML is implemented.
    every annotation put on a page (either loaded from a pdf or created
    internally is loaded and saved when opening/closing a document).
    Attributes are dumped to XML and reloaded from it via qdom
  DataStructures: internal changes, better naming, some attributes fused.
    PopupAnnotation has become WindowAnnotation
  PDF16Parser: 100% completeness for the types we support

PDFGenerator:
  adapted to annotation ds changes. better parsing on a couple of attrs.
  correctly handle 'F'.

Misc:
  Document: remove/cleanup debugs, Page: performance testing stuff added,
  PagePainter: setPen( annot->color ), PageV..or: typo,
  TODO: many changes
