Pillow 3.0.0 drops support for tostring() in favour of tobytes()

Using the most up to date Pillow (3.0.0), using VideoFileClips resize method fails with the following traceback (only relevant bit shown):

Take a look at the latest build. The relevant lines are comment out. If you follow the trace this error occurs at line 32 in resize.py. You can change that to use tobytes() or update the file to the latest file in master. This solved the problem related to the resizing issue I had.

Changing resize.py works for now without issue. I'll wait until the next release to upgrade my moviepy to keep my pip environment clean but I'm sure it'll work.
