Some related tasks with bookmarkable URLS (maybe split then in other JIRAs)

• For URLs bigger then 2000 chars, store then on VFS
• Make it work with goto(PlaceRequest, "div id")
• Create a API for screens store additional state on the url
• We should also track parts:
  final PlaceRequest projectScreen = new ConditionalPlaceRequest(LibraryPlaces.PROJECT_SCREEN)
  .when(p -> (Boolean) hasAssets)
  .orElse(new DefaultPlaceRequest(LibraryPlaces.EMPTY_PROJECT_SCREEN));
  final PartDefinitionImpl part = new PartDefinitionImpl(projectScreen);
  part.setSelectable(false);
  placeManager.goTo(part,
  libraryPerspective.getRootPanel());
