Changing Groups while 'Clear' is Active does not Cross-Fade

[GoogleCodeExporter]

- Send a group to the output and some text. Click clear, verify clear is
active (just BG showing on output now.)
- Send a different group to the output with a different background (so you
can see any change in BG)
- It doesn't cross fade to new BG, just "cuts"

Original issue reported on code.google.com by josiahbryan@gmail.com on 23 Jan 2010 at 5:04

Caused by an errant connection in SlideGroupFactory.cpp/SlideGroupListControl 
to the
selection model's currentChanged(const QModelIndex &, const QModelIndex &) 
signal -
which was disconnected by changing to sel-model in the song slide group view 
control.
This extra connection caused the slide to be set twice upon going live - this 
caused
the clear cross fade to jump to the end of the transition prematurely.

Fixed in r481. 
Quoting Comment from MainWindow.cpp:

I think I've coded my own API under an incorrect assumption - that is, that I 
need to
set the slide group on the instance instead of just letting the 
SlideGroupViewControl
set the slide group - which now seems the more logical method. Therefore, I've
removed direct calls to OutputInstance::setSlideGroup() from MainWindow::* 
methods,
and instead will rely on SlideGroupViewControl to set the slide group on the
outpuTInstance that it is responsible for managing.

Also had to adjust SlideGroupViewControl to not duplicate calls to
'm_slideViewer->setSlide(s)' - in ::setCurrentSlide, it called
'm_slideViewer->setSlide(s)', then called slideSelected() with a QModelIndex.
slideSelected() then in turn called m_slideViewer->setSlide(s) again with the 
slide
for that index. 

Just FYI.
