PurgeCache by listing by access time rather than modification time,
and limit how many files need to be opened by piping through head.
Control module js now displays content in edit mode that was
previously hidden for logged in users. Improved microformats image
parsing to use lightbox effect more often, also now displays two
of the image set by default, side by side. jQuery UI icons are now
shown for reader items that have been marked up as like-of or
repost-of, to be consistent with in-reply-to. Improved the image
handler used by SimplePie to cache external images. Files where the
image content was previously removed to save space are now re-cached
since the file now has a more recent access time. Also added a new
function to SimplePie to resize large images before they get cached.
