	* app/session.[ch]
	* app/gimprc.c: removed the old dialog session management code...

	* app/widgets/gimpdialogfactory.[ch]: ...and manage all dialogs here.

	* app/gui/dialogs-constructors.[ch]: dialog factory compliant
	constructors for all session managed toplevel dialogs.

	* app/brush_select.[ch]
	* app/devices.[ch]
	* app/docindex.[ch]
	* app/errorconsole.[ch]

	* app/lc_dialog.[ch]
	* app/palette.[ch]
	* app/pattern_select.[ch]
	* app/toolbox.[ch]
	* app/tools/tool_options_dialog.[ch]: all dialog constructors have

	Removed the session management code as this is now done for the
	dialogs, not by them.
