Testing this on 1.14 revealed some issues in the 1.13 support I claimed. Now everything should be fine! Also, I rewrote the custom tree definition system to be more stable and more sane. Instead of 3 separate lists that allowed for IDs, required data and more, we now just use the strings that are supported by the 1.13 API, also we group the definitions together in nested lists. An example will be added in the form of a birch tree.

• v6.0.60 - Custom tree definitions now are in a list of lists in the config, grouped together properly and saved together, in the file and in the API
• v6.0.58 - Finalize the custom tree system so it is operational for now.
• v6.0.57 - Implement addcustom and removecustom in accordance to the 1.13 API - everything is based on strings like minecraft:dirt, should work backwards compatibly with properly defined material values!
• v6.0.56 - Fix mushroom implementation 1.13 compatibility
• v6.0.55 - Fix plugin.yml typos
• v6.0.54 - Fixed a bug where items not explicitly in the tools list could be used to cut down a tree
