VaultInk 0.60.0

Library sort by progress, Random page, paper contrast, faster search, default Library tab, changelog out of the recents (kos25k #15, #1, #24, #18, #9).

• Library: with Recent open, a bar with Recent, ↑% (most read first) and ↓% (least read first). Every book shows its percent next to the author. Settings > Library > Open on tab picks the tab it opens on.
• Random page!: a new Home item, off until you tick it in Settings > Display > Home screen items. Opens a random page of a random book and saves nothing; the arrow goes back to your place.
• Paper contrast: first row of Settings > Reader > Paper Button Cycle, a 0 to 100 slider with a preview of every background.
• Search in Book: the gear is at the right edge and result lines fill the row. It starts at your chapter then wraps, shows the last result again for the same words, and Settings > Reader > Search word > Index books lets repeat searches skip chapters.
• The What's New note no longer stays in the Library's Recent list or on the Home card after you read it.
• Fixed: the first Home after an update showed the CrossPoint home instead of VaultInk's.
