on_damage event not being handled as a detected event

[WolfGangS]

on_damage is not being passed the new DetectedEvent userdata values

I suspect this is due to this set containing "damage" instead of "on_damage"

slua/VM/src/lllevents.cpp

Lines 512 to 522 in ecea738

	static const std::unordered_set<std::string> MULTI_EVENT_NAMES = {
	"touch_start",
	"touch_end",
	"touch",
	"collision_start",
	"collision",
	"collision_end",
	"sensor",
	"damage",
	"final_damage"
	};

Reproduction

1. Create a prim
2. Take a copy
3. Add the copy to the prim's inventory (leave it's name as Object)
4. add this script to the prim

local touchStart = function(detected)
    ll.RezObjectWithParams(
        "Object",
       {
           REZ_FLAGS, bit32.bor(REZ_FLAG_TEMP,REZ_FLAG_PHYSICAL,REZ_FLAG_DIE_ON_COLLIDE,REZ_FLAG_DIE_ON_NOENTRY),
           REZ_POS, vector(0,0,2), true, true,
           REZ_DAMAGE, 10,
           REZ_DAMAGE_TYPE, DAMAGE_TYPE_BLUDGEONING,
        }
    )
end

LLEvents:on("touch_start",touchStart)

LLEvents:on("on_damage",function(a)
    ll.OwnerSay(`on_damage {a} {typeof(a)}`)
end)

5. Click the prim
6. Notice the message on_damage 1 number in chat

Additional

Personally I would prefer on_damage, on_rez, and on_death to drop their on_ prefix, as

LLEvents:on("damage", ...)

Reads cleaner than

LLEvents:on("on_damage", ...)

Thanks for sending this in! Should be fixed by 580a08e . I think we can do something about the on_<whatever> naming through an alias, please file a canny for that.
