Watermark: docx interoperability

Before patch:

Document created in MS Word:
<v:shapetype id="_x0000_t136" o:spt="136" ...>
<v:shape type="#_x0000_t136" ...>

Imported to LO and exported:
<v:shapetype id="shapetype_136" o:spt="136" ...>
<v:shape type="shapetype_136" ...>

Then again imported to MS Word and exported:
<v:shapetype id="shapetype_136" o:spid="_x0000_m1026" o:spt="100" ...>
<v:shape type="#shapetype_136" ...>

In this moment LO after import had shape in the navigator but it wasn't visible.

Patch:
* vmshapecontext.cxx is changed to read ShapeType from id instead of o:spt
                     when o:spid is present.
* vmlexport.cxx added o:spid for Word to identify inserted watermark
* edfxol.cxx changed name of shape to "PowerPlusWaterMarkObject" for Word
* tests
