  * Make cabal upload/check print out the error messages reported by the server
  The code to do it was already there but we were checking for the
  mime type text/plain using just (==) when in fact the server reports  
    text/plain; charset="ISO-8859-1"
  so we have to parse the field a bit better (still a bit of a hack).

    M ./Distribution/Client/Upload.hs -4 +6
