Npc scanner on path

An npc_scanner_on_path prefab.

A prefab located in the Prefabs HL2 folder, containing a setup for a scripted movement of a Combine scanner.

This prefab contains the following:

• An npc_cscanner NPC template to be spawned.
• An npc_template_maker entity to spawn it.
• Three path_corner entities that will mark the path for the scanner to follow.
• An aiscripted_shedule entity that will make the spawned metrocops move to the first path_corner.

The prefab is started by sending a Spawn signal to the npc_template_maker from an external source.
