Subject: [PATCH] widgets: Don't hardcode item column in blink_item ()

In gimp_item_tree_view_blink_item (), we
originally used "3" because that is the
item column in the layer and channel
dockables. However, the path dockable
item column is at "2" since it lacks a
filter column.

To make this more general, Jehan
suggested we create a
gimp_container_tree_view_get_main_column_position ()
function in GimpContainerTreeView that
finds and returns the column index of
the main item. Then, we use that function
in gimp_item_tree_view_blink_item ().
