Not removing trelsb-modal-open when continue is clicked.

Hello,

Loving the plugin, nice and simple. Found that the class .trelsb-modal-open does not get removed when clicking the continue button. Usually not an issue, but when target=_blank is used, it freezes the page in place when returning to the original site.

Found that adding jQuery('body').removeClass('trelsb-modal-open'); to the contInput.click(function() { in the .js file did the trick. Also switched the order of removing the modal and removing that class, just to make sure it got triggered.

Cheers!
