Reduces the size of bpmn-js {Viewer, NavigatedViewer, Modeler}
bundles by roughly eight percent:
* module concat / tree-shake produced production bundle
* bump diagram-js version to fix <this> used in ManhattanLayout
utility
This improves the import and export of BPMN 2.0 XML documents
+ improves di prefix collision handling
+ proper deconflicting of prefixes during export
+ validate and detect non-BPMN root elements
+ replace underlying XML parser for higher speed and smaller
bundle size
+ pass parse warnings with errors
NOTE:
* some error messages on broken XML may have changed
due to changes in the underlying XML parser
