Arcanox Core 5.2.1

This update improves the appearance and behavior of the hybrid and debug UIs. The hybrid battery level (both the visual bar as well as the text) now reflects the "relative state of charge", meaning "0%" is "the minimum working battery level" but not actually a "fully depleted battery", and likewise with 100%. To see the exact/raw state-of-charge of the battery, use the Arcanox Debug app.
