What the ToolStripCollectionEditor should do IMHO is

1) Use reflection to find all classes that are:
      - subclasses of ToolStripItem
      - in a public assembly and are public classes
2) Based on the ToolStripItemDesignerAvailability attribute on each of the
ToolStripItem filter out all that do not match the ((ToolStripItem)
ITypeDescriptorContext.Instance).Owner type.

Now the problem is that ITypeDescriptorContext is not known - not until
EditValue is called, so overriding CreateNewItemTypes won't work because it is
called prior EditValue. You will have to create a new custom
CollectionEditor.CollectionForm where you will be able to override
ShowEditorDialog, because at this stage you will be able to access the Context
property of the CollectionForm and do what I explained above to populate some
sort of a list of allowed toolstrip items to create.

That way the editor won't have any hardcoded values.

Also tests won't be required (won't be possible anyway) when the editor is
implemented that way.
