Title: added .clone() method to cameras

Since it was not implemented, I decided to add the .clone() method to Camera, OrthographicCamera and PerspectiveCamera. Can be useful to create a 'snapshot' of an existing moving camera for example.
This is my first pull request for this project, I hope I did it correctly ;)
