[Bug-gnupod] New "--podcast-artwork" feature.

[H. Langos]

Here's another new feature for podcast support. It allows you to 
automatically download the podcast's artwork and add it to the 
podcast's files.

Due to limitations in the current implementation you can't add
different pieces of artwork during one run of gnupod_addsong. So you 
can't add different artwork for different podcasts in one go yet. 
But I guess that most people run gnupod_addsong in a script anyway.
( I would like a hand here from somebody who understands the artwork 
related code in gnupod.)


To cleanly apply you'll first need the patch as attached to this 
email: fix_a156511d_Change_size_tolerance_for_podcast_cache.patch


The patch for podcast-artwork itself is attached as

PS: You've got to love "git" it can generate and process patches in
emails (I'm not using this yet) and even export changes you've made 
to your local repository, back to the cvs server where you imported from.

    Added "--podcast-artwork" option to download and add artwork to podcasts.

    It will try to get the picture referenced by the channel element
    "itunes:image" or "image".

    I had to make the "DropUnseen" option that removes unused artwork from
    the artwork database depend on the non-usage of "--podcast-artwork" because
    otherwise every cover but the last would get deleted.

    Detail: The information about artwork usage is read during parsing
    of GNUtunesDB.xml meaning that at this point the artwork database has
    to be loaded. However you can only add artwork BEFORE loading the
    database. This works well on the commandline where you already have
    the artwork in a file. For podcasts you have to work with data from the
    GNUtunesDB.xml before you even download the artwork. Impact on normal
    users should me minimal.
