Log Message:
Update to 2.59. From the changelog:

- Total rewrite of email code that should fix encoding problems

- Added configurable timeout for nonresponsive feeds

- Fixed incorrectly using text summary_detail instead of html content

- Fixed bug with deleting feed 0 if no default email was set

- Print name of feed that is being deleted

- Finally added oft-requested support for enclosures. Any enclosures,
    such as a podcast MP3, will be listed under the entry URL

- Made feed timeout compatible with Python versions 2.2 and higher,
    instead of v2.4 only

- Added optional, configurable CSS styling to HTML mail. Set
    USE_CSS_STYLING=1 in your config.py to enable this. If you want
    to tweak the look, modify STYLE_SHEET.

- Improved empty feed checking

- Improved invalid feed messages

- Unfortunately, rss2email is no longer compatible with Python v2.1.
    Two of the most serious lingering issues with rss2email were
    waiting forever for non-responsive feeds and its inablility to
    properly handle feeds with international characters. To properly
    fix these once and for all, rss2email now depends on functionality
    that was not available until Python v2.2. Hopefully this does
    not unduly inconvenience anyone that has not yet upgraded to a
    more current version of Python.
