Double util throw positions as spawn points for designated team

[mavproductions]

Hey @zwolof @B3none !

Allow Util positions to be doubled as spawn points for the designated team the util belongs to.

To avoid conflicts with spawn ID, maybe create a new field in Util entries for spawn defaulted to null then config creators can designate it to an open spawn ID.

Maybe append spawn_type as defaulted null as well?

Let me know what you think!
