[Interest] Loader refresh

[md at rpzdesign.com]

Listers:

I was able to loop through the children recursively and find that the 
"QQuickText" Classnames were the candidates to try to execute:

QMetaObject::invokemethod(gobj,"doLayout",Qt::QueuedConnection);

But it had no effect on the currently displayed text.

That has to be some less intrusive way to cause QML gui objects to 
repaint themselves.

Any ideas instead of Loader:sourceComponent, which is very heavy and 
causes screen flicker.
