f12d3b34778f: Update BListItem::SetHeight() docs with selection box warning.
The cached top coordinate of each BListItem isn't updated when you
change the height of the item, leading to confusing highlighting and
incorrect mouse clicks. Rather than fixing it, this just documents a
workaround or two to force an update of the cached coordinates.

\param height The height to set the list item to.
+ \note Unlike BeOS, if you change the height then you need to force
+ the BListView to recalculate the cached tops of the item
+ selection boxes, otherwise selection highlights will be drawn
+ in the wrong places and mouse clicks will be misinterpreted.
+ You can do this by adding and removing a dummy BListItem at
+ the top of the list, or after hrev50780 by calling
+ BListView::FrameResized() with the current Frame rectangle
+ (though the FrameResized() method will additionally call
+ BListItem::Update() for all items).
