Modify atom change feed so that

1.  It returns the last 14 days of changes rather than the last 20
2.  Change the atom template so that it has correct time offsets rather than saying that PST and UTC are the same
3.  Change the atom template so that it uses content rather than summary and return HTML content with line breaks as needed.
