[scribus] XPS exporter and multi-page XAR importer available and ready for testing

Hi all, As of yesterday, Scribus 1.5.0svn provides an initial version of an XPS exporter. It hasn't any options like the PDF exporter yet, but seems to be working pretty well already. Franz has also enabled multi-page XAR import, so documents from Xara Designer (Pro) and Xara Page & Layout Designer can be imported and edited directly. Happy testing! Christoph
