Script callback system

• Table intercepts stores function names that fire on callbacks;
• RegisterScriptCallback registers a callback;
• UnregisterScriptCallback unregisters it;
• SendScriptCallback sends a callback.

Example usage:

-- available callback types
local intercepts = {
	save = {},
	load = {},
	update = {},

	save_state = {},
	load_state = {}
}

-- script
function DoSomething()
    -- ...
    SendScriptCallback("save_state")
end 

function DoSomething2()
    -- ...
    SendScriptCallback("load_state")
end

-- binder
function actor_binder:reinit()
    -- ...
    RegisterScriptCallback("save_state", self)
end

function actor_binder:net_destroy()
    -- ...	
    UnregisterScriptCallback("save_state", self)
end

function actor_binder:load(reader)
    -- ...
    self:load_state() -- fake call because binder is not ready during callback
end

function actor_binder:save_state()
    -- ...
end

function actor_binder:load_state()
    -- ...
end
