	* app/widgets/gimphelp-ids.h: added help IDs for the libgimp
	export and unit dialogs.

	* libgimp/gimpexport.c
	* libgimpwidgets/gimpunitmenu.c: replaced html links by the new
	help IDs.

	* plug-ins/*/*.c: replaced all html help links by help IDs. A
	plug-in's help ID is its procedure name with '_' relaced by '-'.

	(e.g. file_tiff_save's help ID is file-tiff-save)

	Did some random indentation and whitespace cleanup.
