Add all button for bundle results

When a user query results in a bundle that contains graphable entities it would be nice to have an "Add all to graph" button on the bundle. So if the bundle contained an edge and two vertices it would add all of those in one click.

Requirements

• Do not show the add all button when no graphable entities are within the bundle
• When a subset of bundle entities are added
  • The button should be an add button
  • When clicked it adds the remaining entities
• When all entities are added to the graph already
  • The button should be a remove all button
  • When clicked it should remove all entities from the graph that are in the bundle
