Clean up mod_autoindex's storage of the IndexOptions settings.
	They are per-directory, not per-filename, so keeping them in
	an array is confusing and pointless.  They're now stored in an
	int in the module config record.  Also (finally!) fix the
	FancyIndexing directive so it gets merged into any IndexOptions
	settings for the current directory, rather than replacing them.
