libmso: Merging mswordodf/graphicshandler stuff into libmso.

* The defineGraphicProperties f. is now completely merged. However the following graphic-properties
attributes require testing in stage and tables:
style:horizontal-pos, style:horizontal-rel, style:vertical-pos, style:vertical-rel

* Shapes which are still processed by graphicshandler use the client interface so dashStyles work!
There's too much differences compared to the other filters (ppt,xls) to process all shapes by libmso.
