	* gtkrc: set the width of the scrollbar slider to the same value
	as our default font size so the sliders are nicely aligned with
	their descriptive labels.

	* libgimpwidgets/gimpdialog.[ch]
	* libgimpwidgets/gimpquerybox.[ch]: use GLib-isms and create the
	dialogs' action_area buttons with gtk_dialog_add_button() so we
	can use the GTK_STOCK_FOO buttons and plug in our own icon factory
	later.

	* app/qmask.[ch]: fixed the qmask buttons by applying proper
	GdkEvent callback conventions.

	* libgimpwidgets/gimpcolorbutton.c: NULLify all pointers in
	"destroy".

	misc minor cleanups.
