mlbviewer.py fixed

looks like mlb.com decided to jack up the xml they were sending out a couple of weeks ago, and it took me a while to figure out what to do about it. apparently the sourceforge forums are not really used; all the discussion about mlbviewer is at lq. the critical point was in comment 2917:

$ cp MediaService.xsd ~/.mlb

$ rm -r /tmp/suds/*

that suds cache really had me stumped when nothing happened after i updated the MediaService files. and it's really annoying to debug these kinds of problems when the Sign-on Restriction Error locks me out for >15 minutes at a time.
