Upgrade Anaconda from 2.0.1 to 2.3.0

[rodrigosetti]

This upgrade adds newer packages, but specially the iPython notebook functionality that allows uploading files (like images).

@rodrigosetti Did you get something like this when adding your change to the dockerfile? Only happens using Anaconda 2.3.0

If you can add the file uploader as a modification on the python notebook, I'll check it out, build it, give it a quick test, rebuild the docker container and push to dockerhub.

@ryankennedyio I don't get that... but I get a message saying that the notebook is old and it needs updating. I committed the updated version and now it's running without the warning message.
