add support for working with processing movie libs with movieEvent 

This change works in the same way that setup or draw functions, that's to say passing the onMovieEvent function on defsketch. It's added a new clojars dependency to work with gsvideo. This dependency have been modified to work with a method that recieves an Object instead of a codeanticode.gsvideo.GSMovie


Example of working with movie-event behavior
```
(defn movieEvent [movie]
  (println "listen movie event!" movie)
  (.read movie)
  )


(defsketch example
  :title "j"
  :setup setup
  :draw draw
  :size [300 300]
  :target :perm-frame
  :key-pressed keyed
  :movie-event movieEvent
  )
```
