Use drupal modal window instead of ugly js pop window.

I thought I'd post a screenshot of what fullcalendar_view-3256576-5x-modal-003.patch looks like ->

Thanks everyone.

In the develop branch now.

The modal popup at mobile widths being too wide seems to be a theme issue...? See: https://www.drupal.org/project/d8w3css/issues/3177344#comment-13863080 →

The css suggested in #5 there seems to fix it.

You might want to experiment with the media query width and dialog widths, something like

@media (max-width: 800px){
  .ui-dialog--narrow {
       min-width: 85%;
       max-width: 85%;
  }

  .ui-dialog.ui-corner-all.ui-widget.ui-widget-content.ui-front.ui-dialog-buttons {
       width: 85% !important;
  }
}

?

Be great if we could do the same for the jsframe dialog box.

The commit for this task doesn't involve any CSS, so I think it should be a conflict between custom CSS and Drupal modal dialog, or between Fullcalendar theme and Drupal theme.
