Minor fixes for older wordpress and hasty configurers

Version 1.4.5  recently uploaded to wordpress has  two minor changes:

  • For hasty configurers who do not configure the nice names for the list headings, the earlier version would fail on attempting to configure a list without first configuring nicenames.  1.4.5 will check and use default nicenames.
  • For versions of wordpress < 2.8 (and note still greater than or equal to 2.7) the rss feed for updates such as this one about the plugin would fail as it uses function fetch_feed which is new in 2.8.  Alternate logic has been provided.
