Material-ui: incompatibility with react v16

[barbalex]

• [x] I have searched the issues of this repository and believe that this is not a duplicate.

I did find this: https://github.com/callemall/material-ui/issues/6520 which made me believe this should partly be solved.

Expected Behavior

Current versions of material ui should install in current versions of react without warnings

Current Behavior

Run npm i and see:

npm WARN [email protected] requires a peer of react@^0.14.0 || ^15.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of react@^0.14.0 || ^15.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of react@^15.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of react-dom@^15.0.0 but none is installed. You must install peer dependencies yourself.

Check where this comes from:

PS C:\Users\alex\apf2> npm list react-event-listener

PS C:\Users\alex\apf2> npm list recompose

PS C:\Users\alex\apf2> npm list react-transition-group

Steps to Reproduce (for bugs)

• install react and react-dom v16.0.0
• install material-ui v0.19.3
• run npm i
