Add vjs standard

[gkatsev]

So far, this adds in videojs-standard. standard --format is currently broken because it doesn't support the ES6 module syntax.

I'll be working towards making the changes to pass standard.
Addresses #2034.

TODO

• Remove jshint and others
• Update code
• ???
• Profit

@gkatsev how can we continue to make progress on this one?

Would it be possible to do the same thing with just an eslint config?

[gkatsev]

The idea is that you don't need to worry about copying the eslint config. You just npm install -D videojs-standard and then add it to your build.

I guess I mean making a sharable config.

[gkatsev]

That still means that you would need to configure your app to use eslint. With stanard, you just install it and run it. No configurtion, no anything else.
