Update eslint and related dependencies

[realityking]

🚀 Why this change?

eslint and related dependencies are out of date. This updates them to their newest version. Part of this PR was originally part of #969.

This probably can't be merged until there's been a new release of eslint-config-airbnb-base (see #969 for discussion)

Other changes:

• Switch from eslint-config-airbnb to eslint-config-airbnb-base. This project is not using the React related parts and this drops some indirect dev dependencies.
• Fix new style issues due to the update to eslint-config-airbnb-base
• Disable prefer-destructuring. The rule is now part of eslint-config-airbnb-base but this didn't seem worth fixing. (Could always be done at a later time)
• Fix use of the Buffer constructor, also a new error from eslint-config-airbnb-base

This is amazing! Thanks so much. I hope the eslint-config-airbnb-base gets released soon so this PR won't get outdated or won't get merge conflicts.

BTW it looks like there are still some leftovers - the Travis build fails rightfully, on linter.

cli-test.js
336:179 error new Buffer() is deprecated. Use Buffer.from(), Buffer.alloc(), or Buffer.allocUnsafe() instead no-buffer-constructor

@honzajavorek I didn't quite get that far last week but I've made a separate PR for that change as it's independent of the eslint upgrade. See #979

[honzajavorek]

Unfortunately blocked by #1047, #1046, #1045.

[realityking]

Ouch, that's gonna take a while to unblock

[honzajavorek]

Yup.

@honzajavorek Rebased on master and updated everything to the newest version. I know that some of the licensing issues have been resolved but not all of them. Can you re-run the license check?

[honzajavorek]

@realityking I'm sorry, I had vacation, hence the delay. I'll re-check, but recently I did some re-checks because we resolved a lot of dependencies and I think ESlint is still problematic. We're currently hunting down a lot of this stuff, but dev dependencies have lower priority.
