Adds the widgets needed by the theme editor as a jar file that will be linked from AS. The controls currently are: - ThemePreviewLayout: A custom layout that allows to dynamically reflow cards that display the theme preview. - PressedButton: Custom button to display in a pressed state (currently we can only do it programatically). - ErrorCatcher: View that can wrap other view and stops a view throwing exceptions that will break the theme editor rendering. This is currently used to wrap the custom controls loaded from the source code. The new library currently depends on bridge to be able to use the logger for the ErrorCatcher view. The ErrorCatcher view is a temporary solution that will be replaced in a future CL and the dependency will be removed. Change-Id: I832c447e22e1381abff74c46c4282921b3f6fa23
