Animation and Image Utility Updates

• Update: Updated some of the methods in the GUIUtilities to allow for dismissing a keyboard and not just showing it. Also added in an overloaded hideKeyboard method using context + a View.
• New: New methods in the ImageUtilities to allow for setting the Image View Color using tint logic. Also added in a method to determine if a passed color argument is a valid resource.
• New: New overloaded methods in the AnimationUtilities to allow users to pass a callback listener whenever the animation completes.
