Fixed GtkTreeMenu to not infinitely recurse when building submenus.

Browse Source 
GtkTreeMenu needs to only populate it's submenus when set_root()
is called, we were populating it when the model is set which cause
the tree to be infinitely populated as the root is NULL by default.

Also call gtk_menu_set_reserve_toggle_thingy (FALSE) to not reserve
space for the toggle size.
