Artwork deduplication should be done with hashes, not by full data
comparison. This should be a lot faster loading artwork from files now,
especially if the playlist already contains a lot of unique artwork.

Significantly reduce the memory footprint of adding tracks to the
playlist, by coalescing the NSString and NSData objects in the info
dictionaries as they are being loaded in the background, into a common
data set which will then be discarded when the whole job is completed.
