Saves don't record timed events

[darkf]

Timed events are not recorded/serialized, so if a script is relying on them, it will not work properly when loaded again.

An easy example of this is in arcaves, the ants rely on timed events to move. If you save and reload, they will stay still as nothing is triggering their movement.

This should of course save in temrs of game ticks rather than real time.
