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.
More appropriately aligns ourself with the no team option, because the
collideRule team is only a team because it has to be, not because we want
anyone to have any sort of gameplay based relationship.
Also block any options from being set on this team to further enforce that
it is not a persistent team and should not be treated as such.
