tools: move eslint from tools to tools/node_modules

This is required because we need to add the babel-eslint dependency
and it has to be able to resolve "eslint".
babel-eslint is required to support future ES features such as async
iterators and import.meta.

+Extend like a boss
+
+xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
+
+## Examples
+
+```js
+var extend = require("xtend")
+
+// extend returns a new object. Does not mutate arguments
+var combination = extend({
+    a: "a",
+    b: 'c'
+}, {
+    b: "b"
+})
+// { a: "a", b: "b" }
+```
