Restore aura visuals after loading a save

Saving marks effect objects dead, so after a load the Heldenmut /
Klingenblick buff was active but its aura effect (cObjectFX 842) was
gone. A few ticks after a save game has loaded, the effect is created
again for each such buff of a player hero (CreateAt + cEventFX 0x42,
as the art's cast effect does), with the buff's remaining time.

Shared game events (game/engine/events): engine tick and "save game
loaded" callbacks; the WASD mod uses the tick through it.
