horologion was the wrong book

The Horologion is the Book of Hours: the fixed portions of the services
themselves. This shows the day's commemorations, its fast and its season,
which is a Menologion. Naming it for a book whose contents it does not carry
was a real error and worth the churn to correct.

typikon already uses the word internally, for menologion.py and the data file
it loads. That is not a collision: typikon provides a menologion, this
displays one.

Renamed throughout, not just the repo: the two scripts, the QML component and
its three qmldir modules, MENOLOGION_COLORS, ~/.config/menologion/colors.json,
the eww widgets and scss variables, the waybar class. Verified standalone and
embedded in a foreign shell, and the smoke suite still passes.

Also drops the em dashes from the prose.
