v2.6.6

• new feature --> buildView()
  ** this will return also a Drawer.Result object. The difference the returned result just contains the sliderLayout view which can be added to any view ;). So yeah now you can do everything with the drawer ;).
• new feature --> stickyDrawerItems
  ** they are added to the footer. use them like normal drawer items. their onItemClick event will return less data as normal items
• some fixes
• update android-iconics (tried to fix alpha issue on pre api level 21 devices --> but StateListDrawable has bugs on those devices)
• FIX #167
