TwitterPicker - hideTooltip prop to hide Swatch tooltips

For TwitterPicker, and other components that use Swatch, I would like to be able to disable the title property of the Swatch.

I have not been able to find a workaround with CSS, but this could be solved with a prop that can omit setting a tittle value on the Swatch's div.

Start by tracing TwitterPicker and the other components that use Swatch, then inspect how Swatch sets the title property on its div. Add a prop that controls whether the title is omitted, and verify that enabling it removes the tooltip while the default behavior remains unchanged.
