getChildComponents returns all decendents

[David Healey]

.getChildComponents doesn't just return direct children (as the API doc suggests) it returns every decendent down the chain. I can see this being very useful, but I only want the direct children.

For now I'm looping through the list it returns and manually checking the parent component but I think this should be fixed. Probably behind a preprocessor for those who have been using it.

@David-Healey or perhaps adding an optional parameter bool recursive?
