"Invalid Peer" error on dependencies for Travis builds

[ccjoel]

All PR Jobs are failing due to peer dependencies being too flexible. using ^ and || under package.json. Should lock to a fixed react version to fix this:

npm ERR! Linux 3.13.0-40-generic
npm ERR! argv "/home/travis/.nvm/versions/node/v4.2.6/bin/node" "/home/travis/.nvm/versions/node/v4.2.6/bin/npm" "install"
npm ERR! node v4.2.6
npm ERR! npm v2.14.12
npm ERR! code EPEERINVALID
npm ERR! peerinvalid The package react@15.3.2 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer react-addons-test-utils@0.14.8 wants react@^0.14.8
npm ERR! peerinvalid Peer react-dom@0.14.8 wants react@^0.14.8
npm ERR! peerinvalid Peer enzyme@2.5.1 wants react@0.13.x || 0.14.x || ^15.0.0-0 || 15.x

I guess react@15.3, while also using fixed versions for enzyme et al would work?
