Release Name: 0.9.93

Notes: In this update: We now use rchardet 1.1 or higher. rchardet has a major bug. We now use hpricot 0.5 solely. 0.6 breaks our tests, and I have not yet played with it. I'll have this for 0.9.94, hopefully. The beginnings of support for Yahoo Media RSS. Right now we support simply media:content and media:thumbnail, and media:content must be both a start and an end tag. Fixed a major bug in the handling of body, xhtml:body, content:encoded, fullitem and prodlink end tags
