Show news headings in the /home sidebar when the main news div is hidden

Browse Source 
Note: this now refreshes along with the rest of the sidebar, so the news.xml
file is read once every 15s - it may be better to cache the headings somewhere,
though it's debatable whether reading the cache file is better than reading the
news.xml file...
