Starts using AsyncTasks. Paused the work to convert this into an ImageView and use a different approach.
Modifies the project's logic. Instead of a helper class, it is now a cached ImageView and can be accessed directly via XML. Now the project is called WebCachedImageView.
Moves WebCachedImageView to the android.view package, to avoid using a full package declaration on XML.
Amendments and bug fixes after testing.
