Subject: Fixed the chr_inv_count function to handle equipment.

the function can now count in the inventory
and/or the player's equipment.

I also fixed the script function and added a use case
in the example map.

+ Fixes after Ablu's review.
+ 2nd fix after Ablu's review: Fix the inventory remove behaviour.

Resolves: Mana-Mantis #288
