v10.0.0

Small breaking change: add a peerDependency starting from the ESLint version that added a parser feature that we were monkeypatching before (and drop that code). If already using ESLint 5 shouldn't be any different.

• Bugfix for TypeAlias: #584

/* @flow */
type Node<T> = { head: T; tail: Node<T> }

// or 

type File = {chunks: Array<Chunk>}
type Chunk = {file: File}

• Update to test against ESLint 5, add a peerDependency: #689
• Drop monkeypatching behavior: #690
