App v0.2.27 and gateway 0.1.23

Skip Intro from Emby's own chapter markers, trickplay seek previews from
BIF files, a server-composed home hero ranked on Radarr/Sonarr dates and
review scores, and My Alerts as its own page behind the user picker.

Related titles now degrade at every step instead of returning empty, and
the "+" is back on Manage users so a second viewer can be added from the
launcher.
