Merged modified patch from maemo-gtk that allows to disable toolbar

	Merged modified patch from maemo-gtk that allows to disable
	toolbar animations. Addresses bug #142582.

	* gtk/gtksettings.c: added boolean property "gtk-enable-animations".
	(patch from Christian Neumair)

	* gtk/gtktoolbar.c: don't animate toolbar changes if the settings
	property is FALSE. Replaced the individual "notify::foo"
	connections to GtkSettings by a single "notify" callback and
	dispatch internally.
