Make component.createObject require a parent argument

For graphical objects (the common case) a common mistake is to not
parent a dynamically created item. Since you almost always want to add a
parent, and it's hard for a beginner to diagnose this problem, a parent
is now a required argument and dealt with by the createObject function.
