* Added a 'FEEDS.SHA1_HASH' field to the database. * Incremented the database version to 368. * Added 'RDFeed::sha1Hash()' and 'RDFeed::setSha1Hash()' methods. * Added a 'RDSha1HashData()' function. * Optimized the podcasting subsystem so as to upload feed XML only when the XML contents have actually changed.
