Matthias Clasen 5f7485f647 gtk-demo: Drop use of deprecated api 
There were several uses of gtk_tree_view_set_rules_hint here.
Just drop them, the theme was ignoring them anyway.

/* Tree View/Tree Store
*
* The GtkTreeStore is used to store data in tree form, to be
* used later on by a GtkTreeView to display it. This demo builds
* a simple GtkTreeStore and displays it. If you're new to the
* GtkTreeView widgets and associates, look into the GtkListStore
* example first.
