Sync actions between table and graph

[jporter-dev]

Actions to sync and consolidate:

• Expand/pin
• Hover/highlight
• Add module actions to expanded table row
• Search and show/hide nodes

[jporter-dev]

To get started on this, need to...

• Decouple actions from the events for hover/drag/click/dblclick
• Make generic functions that handle the actions that the events currently call individually
• Move away from acting on the event object
