	* app/core/gimpimagefile.[ch]: save the number of layers in the
	thumbnail and show it in the description.

	* app/gui/file-dialog-utils.[ch]: added file_dialog_new() which
	contains a lot of factored out code from file-open and file-save.

	* app/gui/file-open-dialog.c
	* app/gui/file-save-dialog.c: use file_dialog_new(), reduce use of
	global variables, added utility functions to reduce code
	duplication, cleanup.

	* app/gui/file-open-dialog.c: use a temporary imagefile to create
	previews so the dialog's preview can show the progress when
	creating many thumbnails.
