Add history imagery under large imagery view.
Allow users to click on history imagery thumbs to set main image and pause the imagery view.
Allow users to unpause and continue imagery stream.
Users can adjust the height of the imagery panes, and the user selected height is persisted.
Implemented auto-scrolling historical imagery view in ImageryController. Imagery domain objects now request historical data on each manual bounds change. Added new specs for ensuring that historical data is requested on bounds change and duplicate bounds / datum are ignored.
