Modifications

• Added '__override' metamethod that is called when a existing key in a table is asigned a new value
• -> If __override exists gets called and the default asignment is cancled

Example:

local t = {}
setmetatable(t, {
    __override = function(table, key, new_value, old_value)
        print("override", key, new_value, old_value)
    end
})

t.a = 1
print("a value", t.a)
t.a = 2 -- __override gets called default asignment is cancled
print("a value", t.a)

-- stdout:
-- a value 1
-- override a 2 1
-- a value 1
