[TextKitDemo] Fix ctor, we must use initWithCoder when loading from a storyboard

initWithCoder: is the designated initializer for views built from the storyboard
since we are not creating the Cell programatically by calling
RegisterClassForCell we must export initWithCoder: ctor to unmanaged world so
when it needs to create a new cell it calls into our managed initWithCoder:
and do the initialization we want.
