verifyLabel should create a label tag instead of paragraph

[zeroedin]

options.verifyLabel should create a <label> tag referencing the <input>. The input will need also need a id attribute as well.

var verification = $('<input/>', {"type": 'text', "id": "confirm", "class": settings.verifyClass}).on('keyup', function () {
  commit.prop('disabled', !isMatch($(this).val()));
});

...

if (options.verifyLabel)
        body.append($('<label>', {text: options.verifyLabel, for: 'confirm' }))
