Fixed the compilation without maemo gtk adding ifdefs with MAEMO_CHANGES define to the code, we have to check this version more carefully.

* examples/Makefile.am: Added control to avoid some examples that
	just make sense with maemo gtk.

	* src/hildon-gtk.c:
	* src/hildon-gtk.h: Remove some functions that use the maemo gtk
	hildon modes with the define.

	* examples/hildon-edit-toolbar-example.c,
	(create_icon_view): Create the icon view without hildon-gtk
	helpers if we are not using maemo gtk.

	* src/hildon-touch-selector.c,
	(_create_new_column): Create the treeview without hildon-gtk
	helpers if we are not using maemo gtk.
