Addition of cover type "liner"


I'd like to suggest the addition liner as a cover type


A problem could be that not all file and tag types support more than 2 cover types and that the other cover types are defined by the id3 standard. So that standard would have to be modified.
And finally, the player also has to support the new type - as otherwise you would not see it.

Thanks for explaining this. Other makes sense since id3 doesn't recognize liner.
