/* preventCopy()
 * Prevents user from copying the text from form fields, either by copy/cut or dragging and dropping text.
 * Binds preventDefault() to oncopy and oncut events.
 * Binds event that makes all fields in selector readonly for onmousedown event. (Doesn't make target field readonly.)
 * Binds event that removes readonly for onmouseup event.
 * MSIE bug requires a user to click twice after readonly has been removed. Focus() doesn't work, use select().
 * I specifically allowed pasting because the issue is really the copying.
 * @param selector string required - jQuery selector for form field(s). As allowed by jQuery, this is typically a list of selectors in one string.
 * @return void
