Plan for 8.x-1.3

Problem/Motivation

Before we move on to the 2.x version of ligthgallery, we need to provide some stuff before, at least be compatible with the last 1.x version of lightgallery. The latest 1.x release was the 1.10. The goal here is to update the code be compatible with 1.10 and drop drupal 8 support.
