React 15.2.0 and unknown props

[vdh]

React 15.2 added some (rather obtuse) warning messages about unknown props:

Warning: Unknown props `autoshow`, `forceGemini` on <div> tag. Remove these props from the element. For details, see https://fb.me/react-unknown-prop
    in div (created by GeminiScrollbar)

@noeldelgado I didn't make any changes in #26 to dist/index.js, I only touched src/index.jsx, so it'll need a rebuild.

@vdh, are you sure? I didn't test it, but I checked the build and didn't find any reference to autoshow or forceGemini on the render method. I will make a quick test though.

@noeldelgado I created #27 to rebuild the fix into dist/index.js.
