Title: Change several "Nope" kicks to something more descriptive.

When players get kicked for an illegal position, the server gives them the reason "Nope!", which is rather confusing for players when this is caused by a bug in a plugin, and can make it more difficult for players to file a bug report.

Several illegal-action kicks describe what the player did to violate the protocol with (Hacking?) at the end, and I have made these follow that pattern in order to give players something better to report to developers or server owners (as well as aiding in debugging). Yes, I know that the kick is logged with a proper reason but having a proper kick reason is better for everyone involved.
