Refactored Reader module and SimplePie Parser to handle microformats

more cleanly. Some properties are now stored using Media RSS extension
so that they can be accessed as enclosures using SimplePie API. Also
moved custom lightbox code to Reader module. Image handler needs to be
the full url for Microsub clients. Other changes are mostly formatting
and a few small bug fixes.
