Since v3.3.0, the space key no longer works in input[type=text] within dropdown menu

Created by: beingawesome

The first line of 'Dropdown.prototype.keydown' was updated to eat spaces. This prevents the user from entering a space in an text element in a form that is in a dropdown.

v3.2

Dropdown.prototype.keydown = function (e) {
    if (!/(38|40|27)/.test(e.which)) return

v3.3

Dropdown.prototype.keydown = function (e) {
    if (!/(38|40|27|32)/.test(e.which)) return
