ZRP controller kill function for AMK/ZoA

-- ZRP's debug mode allows killing online controllers to avoid the animation crash listed here:
-- http://www.metacognix.com/stlkrsoc/CrashesStillInTheGame.html

-- This "patch" ports the ZRP kill function to AMK or any other mod that is not compatible with ZRP.
-- Hit ESC + K in game to kill all online controllers.

-- Add this to main_menu:OnKeyboard(dik, keyboard_action) in scripts\ui_main_menu.script (e.g., on line 291 in AMK):

        if dik == DIK_keys.DIK_K then
        if level.present() and (db.actor ~= nil) and db.actor:alive() then
                console:execute("main_menu off")
                local kill_count = 0
                for id_ = 0, 65534, 1 do
                    local lobj = level.object_by_id(id_)
                    if lobj ~= nil then
                        if lobj:clsid() == clsid.controller_s then
                            if lobj:alive() then
                                lobj:kill(lobj)
                                kill_count = kill_count + 1
                            end
                        end
                    end
                end
                local msg_text
                if kill_count > 0 then
                    msg_text = "Controllers killed:  " .. tostring(kill_count)
                else
                    msg_text = "No online controllers found"
                end
                local hud = get_hud()
                hud:AddCustomStatic("main_task", true)
                hud:GetCustomStatic("main_task"):wnd():SetTextST(msg_text)
                hud:GetCustomStatic("main_task").m_endTime = time_global()/1000 + 7
            end
        end
