dropped portal_types update from stored file, viewAddInstance updates that via setConfigurationDict. minor clean-up

Graphic editor: previous mistake corrected node->edge. removeElement corrected - node_id_to_dom_element_id updated correctly on element remove

new intro-page, inputList and add new model are present in the same page. Default getConfigurateion from server not updated yet. Buggy back to parrent as list does not update correctly. Storing lastSession in local storage. DreamInstance document to be dropped

fixup! Graph editor: remove node_id from node_id_to_dom_element_id when node is removed (from Ioannis)

Graph Editor: event handling promise where not in the tree of promise, so errors in those promise where silently ignored

Also fix the bug that data is not updated before beeing sent to simulation
server
