add possibility to disable all xeh on an object

[commy2]

As requested by MrSanchez. This adds the possibility to disable all XEH on a specific unit. He needs this for some zombies.

    class B_Soldier_base_F;
    class B_Soldier_02_f: B_Soldier_base_F {
        class EventHandlers;
    };
    class B_soldier_AR_F: B_Soldier_02_f {
        class EventHandlers: EventHandlers {
            class CBA_Extended_EventHandlers {};
        };
    };
