add versionify transform to add version to plotly.js dist files:

- task bundle.js uses the verisonify transform to
  insert to package.json version in exports.version
- watch builds don't use the versionify transform because
  it breaks source maps webpro/versionify#11
- the exports.version placeholder is set to 'see pacakge.json'
