Adds /paper command for reloading the paper config.
Closes GH-639
Per-world config logging has been removed in favor of all or nothing
logging for all paper settings. I don't believe it was used enough to
warrant maintaining. If this is not the case it should be possible to
re-add it.
Brought our multiple TNT change patches into a single patch and
configuraiton section.
You /will/ need to update your configs, sorry.
Adds additional configuration and features as well.
