• Images in ligtboxes now have an alt attribute set. The content is configurable through the data-lity-desc attribute on the opener element.
• Initial focus is now set on the dialog element, not on the first focusable element inside the content. This prevents inline content scrolled down if the first focusable element is at the bottom of the content.
• The global click event is now namespaced as click.lity for easier unbinding.
