config: add merge_media_dirs option

By default, if there are multiple media directories specified, there
will be entries for each one in the root directory container.  If
there is only one media directory specified, then just its contents
will be in the root container, to save one level of browsing.

Setting this option changes the default behavior so that multiple
media dirs will behave like a single media dir.
