New features and improvements

• TabbedPane: In scroll tab layout, added "Show Hidden Tabs" button to trailing
  side of tab area. If pressed, it shows a popup menu that contains (partly)
  hidden tabs and selecting one activates that tab. (PR #190; issue #40)
• TabbedPane: Support forward/backward scroll arrow buttons on both sides of tab
  area. Backward button on left side, forward button on right side. Not
  applicable scroll buttons are hidden. (PR #211; issue #40)
• TabbedPane: Support specifying default tab layout policy for all tabbed panes
  in the application via UI value TabbedPane.tabLayoutPolicy. E.g. invoke
  UIManager.put( "TabbedPane.tabLayoutPolicy", "scroll" ); to use scroll layout.
