Trigger revalidate/repaint on updateMonitoredGUI in InfoView

InfoView currently refreshes significant portions of its GUI during updateMonitoredGUI calls, but does not trigger 
revalidate/repaint; this means that the user does not see these changes immediately (they must resize frame or similar). This adds revalidate/repaint calls to ensure changes to the Swing hierarchy are displayed promptly

This issue is generally not observed as updateMonitoredGUI is rarely/never called for InfoView using MCT's current approach to changes (which are generally isolated to the view). However, this is needed to support nasa/MCT-Plugins#8 (Timeline behaves similarly to Canvas in that changes in the Inspector need to be reflected in the center pane; unlike Canvas, InfoView is not suppressed)
