Fix dependencies for react

[LudovicF42]

Need to fix dependencies for react :

• Set react and react-dom as devDependencies instead of dependencies
• Set react and react-dom as peerDependencies
• Add react v16 compatibility

I believe that this is already in the master branch, the only thing left to do, is to make a release, which is already noted in #37.
