	Some code review:

	* app/config/gimpconfig-deserialize.c
	* app/config/gimpconfig-serialize.c: removed obsolete code which
	made sure serialize_property()/deserialize_property() are only
	called for properties of the correct class. We do it the right way
	for quite a while now and clear the inherited function pointers in
	gimp_config_iface_base_init().

	* app/config/gimprc.c (gimp_rc_dispose): don't forget to chain up.

	* app/base/gimplut.c
	* app/base/lut-funcs.c
	* app/config/gimpconfig-deserialize.c
	* app/config/gimpconfig-serialize.c
	* app/config/gimpconfig-types.c
	* app/config/gimprc.c
	* app/core/gimp-modules.c
	* app/core/gimpbrush.c
	* app/core/gimpcontainer.c
	* app/core/gimpdocumentlist.c
	* app/core/gimpitem.c
	* app/gui/about-dialog.c
	* app/gui/color-notebook.c
	* app/gui/gui.c
	* app/gui/tips-dialog.c
	* app/paint/gimppaintcore.c
	* app/paint-funcs/paint-funcs.c
	* app/widgets/gimpcolorpanel.c
	* app/widgets/gimpcontainergridview.c
	* app/widgets/gimpcontainermenuimpl.c
	* app/widgets/gimpselectioneditor.c: removed I/O includes from
	files which don't use lowlevel APIs any more. Also removes
	a whole bunch of G_OS_WIN32 special casing. Removed trailing
	whitespace. Misc tiny cleanups.
