improve ConfigValue([value]) to support lua_type(bool, string, number)

[shewer]

便於 ConfigValue(lua_datatype) 初使化
ConfigValue([nil]).value = ""
ConfigValue([table| userdata]).value = "" with LOG(WARNING)
ConfigValue(true).value = "true"
CanfigValue([number|string]).value = 等同 tostring(value)

[0][./lua/selector.lua:33] → ConfigValue("aoeuao").value
"aoeuao"
[0][./lua/selector.lua:33] → ConfigValue(2).value
"2"
[0][./lua/selector.lua:33] → ConfigValue(2.33).value
"2.33"
[0][./lua/selector.lua:33] → ConfigValue(false).value
"false"
[0][./lua/selector.lua:33] → ConfigValue(true).value
"true"
[0][./lua/selector.lua:33] → ConfigValue(nil).value
""
[0][./lua/selector.lua:33] → ConfigValue().value
""
[0][./lua/selector.lua:33] → ConfigValue({}).value
