IA Page: https://duck.co/ia/view/lastfm_artist

@jagtalon Curious- what do we have to do here? Looks like it's already been ported...

@javathunderman the TopTracks and Albums Spices haven't been updated yet, the code is partially updated, but the Spice API underwent further improvements and the IA's need to match the newest API so that they display results properly (if you take a peek at those screenshots, the results are broken in DuckPAN)
