Support onPaste event on input

[nick-keller]

Idea

It would be nice to be able to pass a custom event hendler for the onPaste event on the input.

Why?

For multiselect it would allow us to parse pasted value as simple tabs / new-lines array to handle pasting multiple values from Excel or from a list. This is impossible to do now since pasting on an input removes all new-lines and tabs characters.

If this idea sounds interesting I can make a PR

I have the same need. @nick-keller , have you find an alternative/workaround to implement this?

Giving the event on onInputChange would be do trick already
