Dino spawning / respawning in own thread

[Metal]

Idea: Dino spawning / respawning could use it's own thread / cpu core.

Impact on server:

Bad: More cpu usage per map if there is server cluster.

Good: There will be "less" lag, if server admins decides to wipe dino or reload (kill) them.

Obstacle: Maybe not possible to hook it up or engine restriction.
