FLOE-115: Start on captions metadata panel.
FLOE-115: In progress commit
FLOE-115: More progress with the captions metadata panel. The only issue is the refreshView() called at captions modelChanged in order to refresh the icon state creates keyboard inaccessible issue since the re-rendering causes the lose of focus. Trying sub-component to render the icon instead of using the protoTree decorator.
FLOE-115: Completed the captions panel and its unit tests.
