Clear current selected value on select-one element

[yabab-dev]

It's more a enhancement than a bug.

Can we have a button to clear current selection on select-one element ?
Like chosen does : https://harvesthq.github.io/chosen/#allow-deselect-on-single-selects

Thanks !

Here is a first attempt : yabab-dev@8d7ad12

I don't if you want a PR or if you want to do on your own ?

If you didn't pass a placeholder and you cleared the current selection, would you expect the element to be blank?

Sorry for the delay, yes :)

This has now been implemented as of version 1.1.5.
