G disabledEquipment

Usage
This variable can for example be set by a map. In the worldspawn, add the key "disabledequipment" and set its value to a comma delimited list of equipment (e.g. "jetpack,lcannon") that is to be unavailable in the armory menu. Binds cannot override this.

With this in mind, see also G_disabledBuildables and G_disabledClasses.
