First concept for the album covers
Shrink the displayed album cover to save memory
Try every available album cover before giving up
Less margin
Generate a unique key for the album cover instead of using the file path
Load the album cover only once
Store the filtered songs in a field to avoid threading issues when the library is currently updated and an artitst is selected
Start a new thread for artwork loading
Fixed references
Updated tests
Make sure that the artwork is already stored in the blobcache before loading it
Fixed library loading and saving
Shutdown Akavache properly
If the artwork loading was successful, don't invoke it again
Store the artwork only if the song has actually been added
Remove the artwork from the cache if the song is removed from the library
Remove the artwork only if the song is removed from the library, not if it is disposed on application shutdown
Explain!
