Implements a generic ClutterActorClone that doesn't need fbos. Many use cases for clonning an actor don't require running a shader on the resulting clone image and so requiring FBOs in these cases is overkill and in-efficient as it requires kicking and synchronizing a render for each clone. This approach basically just uses the paint function of another actor to implement the painting for the clone actor with some fiddling of the model- view matrix to scale according to the different allocation box sizes of each of the actors. A simple unit test called test-actors2 was added for testing.

Move header inclusion guard at the top GCC has some optimization for the inclusion guard, but they only work if the check is the outermost one. We're fairly inconsistent because of historical reasons, so we should ensure that we follow the same pattern in every public header.

Rename ActorClone to Clone/2 Step two: rename the object and its methods. While we're at it, adhere more strictly to the coding style practises; rename :clone-source to :source; add a setter method for the :source property; take a reference on the source actor to avoid it disappearing while we're still accessing it.
