Added variable in SpaceshipMatchData to get track of who last killed you, but it shows wrong person. Need to debug to see if it's a problem only in SInglePlayer in the editor, or if it's another issue.
Fixed bug so now lastKilledBy in SpaceshipMatchData.cs and lastDamager in SpaceshipHealth.cs now point to the right players/objects. Respawn message now says who killed you.
