	* app/interface.c : don't use gtk_drawing_area_size() to avoid
	the defaut size being also the minimum size. Instead use
	gtk_window_set_default_size() on the display shell. Fixes #130982.

	[fixing #131210, but umlauts in the 'main' filename still not really
	 supported on systems where filesystem encoding != utf8
	(Problems with recent file menu and window title)]
	* lib/dia_xml.[hc] : add data_filename() and data_add_filename()
	to deal with possible differnces in filename encodings, see
	g_filename_<to|from>_utf8()
	* objects/standard/image.c : use them.

	* lib/widgets.c : handle possible encoding difference here, too.
	Also get rid of most warnings by using const and GTK casts where
	appropriate; one wrong cast (probably causing a crash) was found/fixed
	by this - the remaining give a hint on finally leaking FontSelectorEntry.

	* lib/widgets.[hc] : hide _DiaFileSelector and *Class in .c. Modified
	dia_file_selector_<get|set>_file to behave like the respective Gtk
	functions do : encoding- and const-wise ;-)
