Added functionality to Attributes to store and update dicts and lists dynamically. One side effect of this is that dicts and tuples need to be stored as custom object types which means that e.g. isintance(obj.db.mylist) == type(list) will return False. In order to do checks like this, use src.utils.utils.inherits_from() instead. The Attribute system now also supports tuples. All other iterables except dicts, lists and tuples are stored and retrieved as lists, same as before.

Available variables in @py environment:

script : dummy script instance
config : dummy conf instance
ObjectDB : ObjectDB class
ScriptDB : ScriptDB class
ServerConfig : ServerConfig class
