Enable recycling of third party preference widgets

Until now we have been recycling only framework preference widgets since
there were no guarantees for third party preferences to support recycling.
This let to broken animations for preference widgets that are outside of
the framework.

This change makes recycling to be used always and in case the developers
need to turn it off they can explicitely use a new attribute that is
being added to the Preference called "recycleEnabled" and set it to false.
