Set visibility on mainItem to match Dialog

Browse Source 
Otherwise we can have an invisible dialog in which the items think they
are visible.

QtQuick is smart enough to not redraw anything if the window isn't
visible, but a lot of bits of our code check the visibility flag to
enable/disable animations. These animation timers do still trigger when
the window isn't visible which wastes CPU cycles.

We are already meddling with the visibility flag so this shouldn't have
too much impact.
