Game crashes if any NPC who must teleport after HF quest is dead.

Fixed with a simple check. Teleport looks for NPC on alive list, but as they are
dead...

Note that Spencer death will still crash the game (Uh, it is a little worse than
just unwinnable apparently).

I think the game shouldn't crash when it looks to teleport a NPC and doesn't
finds it on alive list, but only on dead list. It should report the unhandled
exception, and perhaps even show a console message “attempted to teleport a dead
NPC” yadda yadda “game may be unwinnable or have broken storyline”.

That's why I'm assigning fluzz, moving priority, and renaming title to be more
clear. (And removing keywords)

Jesusalva, could you provide a backtrace of the crash, please ?

And what teleport function crashes, Npc:teleport("there") or
teleport_npc("there", "the_bot") ?

1- Kill Spencer (use VMX Grenade)
2- Warp to map 59 with cheating (HFF)
3- Deploy faulty firmware upgrade
4- Ask for version.

Spencer talks normally, asks you to stand 
by.

5- Leave dialog normally and standby.

> Game crashes.

(It crashed with other NPCs but I was not 
lazy and fixed those less important 
characters...)

Patched pushed in commit 7a43ff815, that prevents to teleport a dead NPC,
informs the player about the bug, and avoids the teleportation.
    
But note that the actual fix would be to check if a npc is alive before to
teleport it, in lua scripts.
