HavenCore's DBC Custom Transformations

The stat items config system has been rewritten to allow future scalability to be done with more ease, this also aims to fix server crashes when having the stat items inside crate plugins.

For each of the stat item's ID (PUItem1, PUItem2...) there will be it's own config file.

With this change you will have to remake your config files (they still have the same behavior as the previous config file)

Fixed arco 5th custom form damage not being calculated properly when using an item.

Fixed incompatibility with CoFH core crashing when starting the game.
