* Update eslint

Updates eslint, babel and plugins to the latest compatible versions

Drops the 'no-color-literals' parameter which doesn't exist (looks like
it's actually part of eslint-plugin-react-native which we don't use)

adding a dirlocal to make sure js2-mode doesn't confuse you with type
errors that aren't actually errors because of flowtype and such

* update generated css classes in snapshots
