Fix exception for CIFilter on MMovieView

- In 10.9 and later OS X requires setLayerUsesCoreImageFilters:
  be called on any views that will have filters attached to
  their layers and will throw exception if not. Looks like
  this only happens if the binary was linked against 10.9
  (makes sense).
- Wrapped this in a guard for when running on older versions
  since we support back to 10.7 still.
