No KILL event for scenery objects

[cfrag]

It seems a recent change has done away with kill events for map objects, doing away with the ability to attribute a map object kill to a player. Now only dead events are invoked for the map objects, making it impossible to tie a map object kill to a player. 

This change makes it much harder to write engaging missions, please bring the KILL event back (and while you are at it, please also restore it to the scenery objects that have dropped invoking the Kill event in favor of Dead/Unit Lost).
