Don't re-render when calling swatchify multiple times

[tatemz]

When I have a <div class="swatch"> and I run $('.swatch').swatchify(); multiple times on the same DOM element, multiple swatches are produced. Would be great if swatchify() checked if the DOM element has already rendered color swatches to avoid cloning swatches.

Additionally, it would be ideal to have the DOM element recalculated to take changes to the data-colors attribute into account. This may hinder performance, so perhaps a swatchify( recalculate = true/false ) might be advisable.

I agree with everything you've said. Unfortunately, I don't have much time to actively support this plugin anymore - but will gladly accept a working pull request :)
