TransferList / RenderList Button

[lkspencer]

It would be nice if the RenderList Component did not use a button as the wrapper around the item component. I know that the general use case for TransferList is managing lists of data, but being able to use buttons inside the TransferList would allow for additional behaviors without react complaining about having a button inside of a button. I've attached an image showcasing what I have put together. I have the buttons and input box in my TransferListItemComponent stop the click propagation, so it doesn't bubble up to the wrapper button.

I feel like the click handling of the list item could be done with something other than a button and then we wouldn't get the warning
