RTL Support

basically you just need to add this file "modal_forms_popup-rtl.css" into css folder with that content:

div.modal-forms-modal-content .item-list ul li {
  margin: 0 1.5em 0.25em 0;
}

div.modal-forms-modal-content div.messages > .messages {
  padding: 10px 40px 10px 10px;
}

/* Styles for modal forms modal */

div.modal-forms-modal-content .popups-container {
  text-align: right;
}

div.modal-forms-modal-content .popups-close {
  right: auto;
  left: 5px;
  text-indent: 9999px;
}

please add it in next release
