[add-art dev] Caching the updated art images

[Jamie Wilkinson]

I'm not totally clear on how this works... so it's an XML file  
embedded in the chrome that contains base64 versions of the images?

It's definitely a step in the right direction, but ideally the XML  
definition would be downloaded and stored in the profile directory,  
read on load, and then the images it references downloaded from the  
server. This way we'd be able to avoid needing to issue an update of  
the extension with each show (and we could theoretically have multiple  
add-art subscriptions loading a large # of possible "shows"  
simultaneously, etc)

So it'd be preferable if the image files were being read from disk  
rather than base64 encoded. Reading from an XML file at all is  
definitely a huge step in the right direction, though! Great work Ethan
