gtk: change GtkIconView to "support" actual trees

Browse Source 
Remove the check for GTK_TREE_MODEL_LIST_ONLY and make the view
display only the first level of the tree, ignoring all insert, remove
etc. events on the model's branches. This enables generic application
code which always produces GtkTreeStores (also for flat lists) to
display grids of these flat trees.

* @title: GtkIconView
* @short_description: A widget which displays a list of icons in a grid
*
* #GtkIconView provides an alternative view on a list model.
* #GtkIconView provides an alternative view on a #GtkTreeModel.
* It displays the model as a grid of icons with labels. Like
* #GtkTreeView, it allows to select one or multiple items
* (depending on the selection mode, see gtk_icon_view_set_selection_mode()).
* In addition to selection with the arrow keys, #GtkIconView supports
* rubberband selection, which is controlled by dragging the pointer.
*
* Note that if the tree model is backed by an actual tree store (as
* opposed to a flat list where the mapping to icons is obvious),
* #GtkIconView will only display the first level of the tree and
* ignore the tree's branches.
