Allows certain simple resolvers to be resolved immediately when encountered (set .__resolve_instant = true).
This fixes a problem with some nested resolvers not being resolved completely before other resolvers are processed.
(This shows up with steam giant's melee_project.FIRE being incompletely resolved while the equipment resolver is run with gear that modifies this field.)

Previously, if the "can_see_cache" property is not initialized when
Actor.canSee() is called, it will be set to a strong table. This seems
bad because this table can hold references to other actors and possibly
prevent garbage collection. Actor.resetCanSeeCache() sets
"can_see_cache" to a weak table, so I think the same should be done for
initializing the property in Actor.canSee().

Now, Actor.canSee() will initialize "can_see_cache" with a weak table
if it doesn't already exist.

I stumbled across this while investigating the Warden's Call memory
leak and found references to the clones in game.player.can_see_cache.
Unfortunately, this change doesn't seem to fix that problem.

use: in hooks/load.lua, call superload("mod.class.Name", function(_M) do whatever end)
works exactly like a superload file except you may do that multiple times
and they will be applied in that order
you still need to set superload=true on an addon
