Don't set spectator flags on dead player objects
Currently in Odamex, when a player spectates, their associated mobj is made invisible.
There is no need to remove a corpse when a player spectates, and in the survival mode that I'm making, where players are forced to spectate if they run out of lives, this behavior causes the player to just disappear when they die on their last life.
The following patch works around this by adding a "deadspectator" flag that is set on the player when they spectate while dead. This alters the behavior of the respawning code, to make it silently respawn the spectator in the same position as their corpse, leaving it behind.

r4867 applies this patch.
Is this implemented as intended?
