* Upgrade eslint
* Pin down eslint version
* Temporary fix for difference between js-beautify and eslint
js-beautify suddenly requires a space between `while` here,
but everywhere else we use it without space.
* Remove redundant rules (present in eslint:recommended)
* Add rules comparable to js-beautify rules to eslint
* Add some forgotten files
* Ugh, fix some differences between eslint and js-beautify the nuclear way
* Add back variables
