Shortcut buttons plugin should not use submit buttons

[tpetry]

The Shortcut Buttons plugin creates normal buttons to confirm or delete flatpickr values. However, since the HTML standard interprets buttons as type="submit" by default, the buttons created by the plugin do not serve their actual purpose.

In my case the enter event on completely independent form elements was evaluated differently from what it should be.

Good catch @tpetry, thanks for the contribution 👍

Could you publish a patch release to npm?

[jcsmorais]

Yes, I'll do it either later today or over the weekend.

I just wanted to remind you nicely on the npm release ;)

@tpetry done 😉
