No longer rely on world time as plugins like to screw it up.
Add a new flag -Dpaper.ticklist-max-tick-delay= that
will automatically drop any tick entries that have a delay
exceeding the specified amount. This is only useful
for cleaning up a world that has been corrupted by
certain blocks having a huge tick delay.
Aimed at resolving #3251
Also fix an issue with some rails connecting incorrectly
that I found when testing.
