Please update this plugin 1.13.

Yes I have planned to work on it next days 😄

I have just created a new branch to prepare the plugin to 1.13 servers, you can check the advancement by following this link: https://github.com/utarwyn/EnderContainers/commits/prepare-1.13

After few tests, I have just seen that EnderContainers 2.1.0 works at 90% on 1.13 servers, so you can use it without major problems. Otherwise, I will try to fully adapt the plugin to use the new features of the 1.13 Bukkit API.

Thanks!
