Martin Gräßlin d03c73a223 Add proper key navigation to layout based window switchers 
The grabbed key events inside TabBox are forwarded to the declarative
view which passes it to the normal keyPressedEvent() method. This
allows the QML files to handle keyboard navigation themselves.

The views support key navigation natively, though this cannot be
used as we need to update the ModelIndex when a new item is selected.
Also there seems to be a problem if the tabbox is shown again, in
that case the focus seems to be somehow lost. Because of that the
navigation is handled in the Item embedding the list.

Rikkus: please document! (Matthias)
Ok, here's the docs :)
You call delayedShow() instead of show() directly.
If the 'ShowDelay' setting is false, show() is simply called.
Otherwise, we start a timer for the delay given in the settings and only
do a show() when it times out.
This means that you can alt-tab between windows and you don't see the
tab box immediately. Not only does this make alt-tabbing faster, it gives
less 'flicker' to the eyes. You don't need to see the tab box if you're
just quickly switching between 2 or 3 windows. It seems to work quite
nicely.
