Update python and moviepy version?

[tomasdms]

First of all thanks for this docker image, it saved me a lot of hours of configuration, I'm using to run it on a aws eb instance and i started to notice a few differences with how moviepy was responding locally after a bit of digging I realize that this image has python 3.4 (not longer supported as of this month) and moviepy=0.2.2.11 also quite old.

I was wondering if you were planning to update this image? Not sure If I feel skill enough to attempt to recreate it myself.

Thanks again!
