Now allowing separate 'published' and 'updated' dates.

Atom links now can have a 'rel' option specified.  RSS links have no
attributes.

Atom IDs are munged links.

Bugfixed a formatting error.

Added 'content' field for Atom, which will put the data in a CDATA block, with
optional type.  This required a bit of ElementTree work, including a subclass
to handle the CDATA.

Bugfixed the timestamp formatting.

Added <?xml...?> tag at begining of output.
