Mychunk reloaded

This update seems to be compatible from 1.8 to 1.13.2. At least the server is starting without throwing any error, but some event may throw errors (I don't think so, but I didn't test everything, so there is always a "chance" of error) 

Added all 1.13 doors/trapdoor in protection detection;

The plugin uses an API class from someone else to allow materials to work with any version.
