Support for MC 1.14

Hello Ollivanders users, sorry for the long delay in posting an update. We've been head-down rebuilding on our server.

This version has been in use for about a year on Pottercraft but we have not been able to test it with other builds, hence the alpha status.

As always, if you find issues, please let us know via github with the "Ask questions/Get support" button.
