Enh #106 : Add an autoPlayVideo user attribute (#159)

Warning : I was not able to run the tests on my machine. It uses a different approach to handle databse connexion and didn't find where to configure it...

- create a migration file to add a boolean column in user table
- add autoPlayVideo attribute everywhere it is needed (both on client and server side)
- add tests
- add a way to configure this attribute in account-settings
- use the attribute in video-watch component to actually autoplay or not the video
