[yocto] [PATCH 4/5] plugins/sdk.ide: Relay events from child widgets to the parent composite

[Timo Mueller]

From: Timo Mueller <timo.mueller at bmw-carit.de>

If the content of the YoctoUISettings changes, because a contained
widget reports a modify or selection event, an corresponding event is
triggered on the parent composite. UI elements containing the
YoctoUISettings can now register listeners and be notified when the
content changes.
