player: add cover-art-whitelist option

This allows more fine grained control over which cover art to load. With
--cover-art-auto=exact and --cover-art-whitelist=yes, you can now load
cover art with the exact media filename and the whitelisted filenames,
but not cover art that contains the media filename
(--cover-art-auto=fuzzy).
