Make free slots display for gear more logical

- Don't show tool slots as available weapon slots in gear. Player is
informed of tool slots count in systemChat.
- Don't show pistol mag slots as available item slots in gear. Player is
informed of pistol mag slots count in systemChat. Only pistol ammo and
bandages can be purchased into them.
- Removed "Stand still to complete trade" message since the medic
animation loop is no longer used
- Added back backpack mags count message and avoided redundant "Backpack
space exceeded message" @oiad
