- In some cases, players are not being kicked, even though their
status clearly indicates they should be. Make sure the "should we
kick them" logic in the status check command matches the logic in
the thing that actually does the kick.
- Clean up the way we handle event hooks to reduce the code mess.
- Don't rely on the bump/bumpn functions returning pname; always
return nil with them and determine pname at the outer layers and
pass it in as necessary. This is how we should have fixed the
earlier bug that caused players digging things not to get the node.
Things like auto-forward or a taped down mining key also count
as "idle" for this system's purposes as well, to avoid players
trivially exploiting to avoid being kicked, or to prevent
false positives caused by stuck controls.
