Use IconView in SmElementsControl

Allows to send individual images over the wire in lok case,
instead of sending full canvas at every scroll operation.

The control's horizontal and vertical modes (when it's docked to a
vertical or a horizontal parent window side) are now identical.

Some TODOs:
* Re-implement a11y - that needs to be implemented on IconView level;
* Make sure that sub-pixel positioning is not used when creating the
elements icons (makes elements look a bit slim on Windows);
* Maybe restore mouse hover indication; in non-GTK case, a call to
m_xIconView->SetHoverSelection would suffice in SalInstanceIconView.
