dhewg fad995722c Implement saving and restoring of event strings
Required for events with string arguments. On debug builds
an assert() is triggered when trying to save such an event,
while events could not be properly restored in any build.

This happens when going from map delta4 to hell1 and the
autosave feature kicks in. The trigger event 'selectWeapon'
with the string argument 'weapon_fists' is in the event queue.

With the binary from id a warning is issued:
WARNING: player1 is not carrying weapon ''
so the bug exists in there too, just that its a release build
and doesn't abort().

I also managed to trigger this while saving shortly after
activating an elevator switch.
