Title: Allow to create empty option in Select

DOES NOT break BC.

This PR adds an option to every Select element in order to automatically prepend an empty option to a select element. This is useful either in a user experience point of view, but most often because a lot of JavaScript libraries need an empty option to render, for instance, a placeholder value.
