Add keys to RangeSlider children

[maedi]

React complains that RangeSlider children don't have key props:

Warning: Each child in a list should have a unique "key" prop.

Check the render method of `ComponentEnhancer(Range)`. See https://fb.me/react-warning-keys for more information.

My RangeSlider component works without issue and looks like:

<RangeSlider filter={props.filter} step={props.step} />

Hi @maedi this appears to be an issue in an upstream package react-component/slider#358. The message you see rendered in the browser console is just a warning and will not affect the functionality of the component.
