JeanZ final feed

Fixed update feed for JeanZ, which ends with 0.1.73-z.26.

JeanZ 0.1.73-z.26 checks this release's latest.json instead of the latest release. It lists z.26 itself, so JeanZ never updates itself into Splitkick. Do not delete this release: every JeanZ install reads it.

JeanZ continues as Splitkick. Install Splitkick next to JeanZ and import your data on its first start.
