Compatibility issue with EssentialsX 2.16.0+

Since https://github.com/EssentialsX/Essentials/pull/2278, EssentialsX has abandoned ItemDb in flavor of ItemDbProvider. This changes also reflect the numeric ID abandon in Spigot 1.13.

So, when I start my server with Magic plugin and EssentialsX 2.16.0(or higher), this shows up:

Not sure if this has any negative effects on Magic-plugin.

Tested with: Spigot 1.13.2 b2065 Magic 7.6.19 EssentialsX obtained from https://ci.ender.zone/job/EssentialsX/ (build 691, 2.16.0.32)

p.s. I thought it was a Ess’ problem but pointed out by one of their contributor named @triagonal, I link the original issue here https://github.com/EssentialsX/Essentials/issues/2396

Released 6.9.20 which works with latest EssentialsX.

That’d be cool, thanks! It’s not a huge deal, I think mainly what my users want is the shop sign integration, though /give working is a nice side-benefit. It’s really cool that I can inject tab-completion, too! Thanks again for putting this together.
