BUG: Filter out unnecessary props rather than pass them through to DOM elements

[stevensacks]

index.js:2178 Warning: React does not recognize the `columnWidth` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `columnwidth` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
    in span (created by Base)
    in Base (created by ThreeBounce)
    in ThreeBounce (at index.js:33)

You are passing through all props that come through the component even when you shouldn't and it results in this warning in the console.

Yes, ThreeBounce doesn't have columnWidth. But it is a valid prop for other types of loaders and you shouldn't pass it through if it's not used.
