Expand eslint rules

[jfurrow]

Let's have better eslint rules.

I think I'd like to use eslint-config-airbnb for the client-side JS and eslint-config-airbnb-base for server-side.

Any thoughts?

Personally I use https://standardjs.com/ - that will be my +1 👍

I'm for the more standard lint rules and standardjs seems to be good for that. Additionally it seems to be supported by some atom plugins like linter-js-standard.

Update: I don't know much of javascript so I don't know the advantage of ESLint but the standardjs can be supported by ESLint with those plugins eslint-config-standard or eslint-config-standard-react.

I created the clean/lint branch where I began to clean the code after doing a npm run lint.

I'm 100% sure for Unnecessary escape character and remove Duplicate key but not for all remove unused value and maybe the strict equality.
