Synchronizes master with wip and fixes debug command (#1066)

## Fixes
* Fixes the `/pk debug` command causing `ClassNotFoundException` and `NoClassDefFoundError` due to missing hook dependencies in the compiled jar.

## Copy Pasted
Credit goes to the authors of all of the changes below. I simply copy-pasted them so that they can be directly committed to master rather than have to re-align the wip and master branches due to them not being synched.
