[Sugar-devel] [PATCH GetBooks] Report when could not reach the server SL #3180

[Manuel Kaufmann]

Handled urllib2.URLError returned by feedparser to inform the user
about this problem, saying that maybe he is not connected to the
network.

If there were another problem downloading the list, the user is
informed with a generic message.
