Regenerate xsl resources in WID

As an update to my post about the xsl resources that could not be found, the generation of xsl mapping files seems even more stubborn than I first thought. The xsl file is indeed generated when the map is tested, but it does not change after you change your actual mapping in the editor. If you test the map again, the previously generated file is used. Even at runtime this is the case.

The one way to regenerate the xsl file for sure is to right-click on the mapping editor, and click "Generate XSLT" (or use the keyboard shortcut Ctrl+Shift+G)
