Old package warnings on install

[kylecordes]

Upon install:

$ npm i -g create-elm-app
npm WARN deprecated babel-preset-es2017@6.24.1: We're really excited that you're trying to use ES2017 syntax, but instead of making more yearly presets, Babel has a better preset that we recommend you use instead: npm install babel-preset-env --save-dev. Give us a follow @babeljs to get more updates
npm WARN deprecated babel-preset-es2016@6.24.1: We're really excited that you're trying to use ES2016 syntax, but instead of making more yearly presets, Babel has a better preset that we recommend you use instead: npm install babel-preset-env --save-dev. Give us a follow @babeljs to get more updates
npm WARN deprecated node-uuid@1.4.8: Use uuid module instead

It would be great to see these go away - probably create-elm-app depends on an old version of something that depends on an old version of these packages.

@kylecordes thanks for reporting this issue!

We will be rolling out the upgrade for Babel presets soon, I'm not quite sure about node-uuid package at the moment.
