Fixed some occuring console errors, oops

Added patrolling mode for both the NPCs, when no target is found or dead targets, the NPCs will wander around the map adding some cool aspects in fun and horror.

You need to have navmesh in the map for it to work since thats how idle navigation works for now, let me know if you encounter a problem.

Removed the need for tweaking the uman's ai, players can just edit the navmesh manually

Made the distance command count for the two nextbots, as well as minor ai changes

New command:
interloper_detectiondistance

Firmly improved the umbrella man's ai, not yet perfect but that's a starting point towards success

Another small bug fix

Tiny bug fix that both chase themes would conflict with each other, when a player spawned interloper for example and removed him, corrupted would play interloper's theme.

Added spawnicons as well as corrupted umbrella man in the game! He will use the map's navmesh to chase you, commands for him at this moment are:

npc_uman_relyonnavmesh (Toggle whenever he will use pathfinding algorithms to chase you: 0-1)
npc_uman_chasevolume (Chase music volume)
npc_uman_chasespeed (Chase speed)

The algorithm at this moment is not very perfect, so expect anomalies along the way

Once you hear a jingle, you're it.

Added "npc_interlopingfr_detectiondistance" command to adjust the nextbot's detection distance ultimately resulting in a more customizable experience.
