Install Hype, the Markdown presentation app, by default (#13455)

Hype joins Omacut, Monologue, Omacalc and Omawrite as an Omacom app in
the base install and the preinstall set, so Remove and Install
Preinstalls cover it too. A migration installs it on existing machines,
unless their owner has removed the preinstalls, and the GUIs chapter of
the manual introduces it.
