According to RFC 4287, there is no atom:url element, only atom:uri, so
replace occurrences of atom:url with atom:uri for compliance.
Also rename variables holding atom:uri from email to uri to better
indicate what they actually are.
This patch ensures the compatibility of setting categories for itunes
podcasts even though the new API now supports setting multiple
(sub-)categories.
It also fixes the docs and adjusts them to explicitly mark the old
syntax as deprecated.
