Add new column `search_radius` to `creature_linking_template`.
If this column is used (value > 0), master and slave are linked together if and only if they have their respawn coordinates within this range (point-to-point distance calculation)
Note that linked spawning is slower this way and should only be used if required

Thanks to Silverice for feedback!
This system interprets the content of the table `creature_linking_template`. To trigger different actions on different events of the npcs that are linked together.
Possible event/ action combinations can be taken form the flags in CreatureLinkingMgr.h::CreatureLinkingFlags
