			-For inspector refresh, the inspector now detects if a property change by polling a few times per second and then does update the control if so. This process is very cheap. -For property list refresh, a new signal (property_list_changed) was added to Object. _change_notify() is replaced by notify_property_list_changed() -Changed all objects using the old method to the signal, or just deleted the calls to _change_notify(<property>) since they are unnecesary now.
