UI issue: don't dumps stack on network error

[elharo]

Sometimes a particular episode fails to download due to a network error outside the control of the program. This should be reported to the end user. However, this does not indicate a bug in the program and it should not dump an exception stack trace to the console.

TimeoutError: The read operation timed out                  

                    The above exception was the direct cause of                 
                    the following exception:

This is a common antipattern in Python CLI programs. Not all exceptions are bugs, and non-bugs shouldn't dump stack traces.

At least one instance of this is here:

https://github.com/janw/podcast-archiver/blob/2aacf1cf20151289dac5b57a41bbe89ea4be4a5e/podcast_archiver/processor.py#L56

The except clause should report the error but not include the root exception

Or maybe disable the logger by default? Looks like user messages are printf'd instead.

Fixed in #189.
