v1.1.0

• New attribute app:rearImageAnimationDelay with relative method.
• Fixed bugs #4 #5 #6.
• Overridden showNext() & showPrevious() methods from ViewAnimator: now they perform the flip accordingly with the existing
  settings and register its state.
• Since the FlipView uses shapes to define its border and shadows, one can use app:frontBackground & app:rearBackground
  for the custom Drawable with the desired shape, color and stroke, which always override inner Drawables.
  Alternatively you can do this also by assigning the resource to android:background of the custom layout.
  Because of that, at runtime, the method setChildBackgroundDrawable(child, drawable) has been reviewed (#2 #3).
• Instead, if you want to use the inner Drawable (OvalShape) and only change color with alpha value, you can do it
  at design time with app:frontBackgroundColor & app:rearBackgroundColor and at runtime with the new method
  setChildBackgroundColor(child, color): it always creates an OvalShape with the custom color (#2 #3).
  Note: setBackgroundColor is the method of android.view.View, so it does the default job!
• First version of ShapeDrawables static methods (Oval, Arc, RoundRect).
• Added new static method to enable/disable logs at runtime, debug logs are disabled by default.
• Added methods to retrieve front and rear ImageViews and front TextView objects.
• Automatic layer type software when setting PictureDrawable for SVG files (applied on ImageView reference only!).
• Adapted example to show Autostart and how 2 entire layouts can be animated ;-)
