Fogwalk v1.9.0

Added

• Delete a journey from the chronicle: its route and record go, the cells it cleared, its finds and coins stay (#43).
• How altars work: a guide from the altars line, with the steps, an example and the limits (#28).

Changed

• Backups carry what you bought: fog styles, gear, wards of the streak and altars move to a new phone too, and merging keeps the more of each side (#22).
• One name for each boost: the grove's gift is the same torch and ward of the streak the shop sells (#42), and the shop says how wide the torch burns: «112 m instead of 70 m» (#40).
