	* app/widgets/gimpdialogfactory.[ch]: added new function
	gimp_dialog_factory_add_foreign() which adds a dialog that was not
	created by the factory itself. Its identifier however must be
	registered with the factory. Connect to all toplevel dialogs'
	"configure_event" and remember the resulting window geometry so we
	get session management for *all* dialogs, not only for those which
	were open on exit.

	* app/gui/dialogs.c: added the "File New" dialog. Added foreign
	entries (without constructor) for all dialogs opened by tools.

	* app/gui/dialogs-constructors.[ch]: added a constructor for
	the file_new dialog.

	* app/gui/file-new-dialog.[ch]: renamed file_new_dialog_create()
	to file_new_dialog_new() and removed the gimage and template
	paramaters. Adder new function file_new_dialog_set() to set
	gimage and template after creation.

	* app/gui/file-commands.c
	* app/gui/templates-commands.c: changed accordingly.

	* app/tools/gimpimagemaptool.[ch]
	* app/tools/gimptransformtool.[ch]: added
	"const gchar *shell_identifier" to the tool structs. Register the
	tool dialogs using gimp_dialog_factory_add_foreign().

	* app/tools/gimpthresholdtool.c: set "shell_identifier" so the
	dialogs become session managed. Fixes bug #61091.

	* app/tools/gimpcroptool.c: register the crop dialog with the
	dialog factory. Fixes bug #52849.

	* app/tools/gimpcolorpickertool.c: ditto.

	Unrelated:

	* app/tools/gimptool.c: no need to cast the return value of
	g_object_new().
