	Bug 547270 – Make GtkHSV public

	* gtk/Makefile.am
	* gtk/gtk.h: install gtkhsv.h as public header (its symbols were
	always public anyway).

	* gtk/gtkhsv.h: add single-include guards, add class struct padding,
	seal the instance member, cleanup.

	* gtk/gtkhsv.c: center the widget in its allocation,
	add "Since: 2.14", cleanup.
