Fixed IconContainer.SetIcon; added ImageContainer

This commit fixes IconContainer's SetIcon, which was SetImage prior to
this commit. Before the code generation commits, this container
originally had SetIcon.

This commit also adds back ImageContainer, which was a regression during
the code generation changes. It has the SetImage method.
