react-d3-zoom had super old peerDependency to react

Hello,

could you update dependency to newer one. People get peerinvalid errors, because of too old react dependency:

```
npm ERR! peerinvalid Peer material-ui@0.15.4 wants react@^15.0.0
npm ERR! peerinvalid Peer react-d3-zoom@1.1.2 wants react@^0.14.1
```

Change following line or remove whole line:

`"peerDependencies": {     "react": "^0.14.1"   },`

BR,
Markku
