Version 4.6 sent to AppStore (Grimmory, nice to have features)

[petrjahoda]

■ New features
- Grimmory. Connect a self-hosted Grimmory server from the Library ••• menu and it does five things at once: browse and download its books with their metadata, send books to it, keep reading status, ratings and progress in step both ways, sync highlights, notes and bookmarks with its Notebook in both directions, and post your reading sessions to its statistics. Signing in also sets up KOReader sync for you. Grimmory 3.1 or newer.
- Customizable reader toolbar. Settings > Reading > Reader Toolbar shows, hides and reorders the buttons under a book, separately for EPUB, PDF, comics and audiobooks, with one icon size slider and a live preview. Hidden buttons keep their keyboard shortcuts.
- Delete several books at once. Select books in the Library and tap Delete: one confirmation with the count, and everything waits 30 days in Recently Deleted.
- Update Metadata from File. A row above Delete in the book menu reads the title, authors, series, tags, description and cover again from the file itself, replacing your edits and keeping progress, highlights and bookmarks.
- Show covers only. A switch under Display in the Home menu draws every shelf on Home as cover art alone.
- Book Sources. Library Display gains Show Calibre, Show Grimmory and Show OPDS switches, so a source you do not use leaves the menus without disconnecting anything.
- 0.05x speed steps. The audiobook and Read Aloud speed sheets open with a stepper between the presets, and the CarPlay speed button cycles to the next preset above.

■ Improvements
- An EPUB counts as finished when its last page is on screen rather than at a percentage, so short books are finished too and no book is finished early after its file was replaced.
- Hyphens now works while Publisher Style is on, so long words break in a book that keeps the publisher's formatting.
- Image-only pages, such as scene-break ornaments and chapter glyphs, stay centered when Publisher Style is off.
- The Sync with KOReader & Kobo help topic now shows Calibre's Kobo driver settings tab by tab, with screenshots, and a Setup guide link in the KOReader settings opens it.
- Get Free Books reads OPDS Books once you have added a server of your own, and Display sits right under Select in the Library menu.
- The Day and Night presets follow light and dark mode only when you set them to. The 4.4 update wired both by itself, which flipped the theme chosen in onboarding, so untouched presets are back to Manual.
- The tap area outline is off by default and, when shown, says where in Settings to turn it off.

■ Fixes
- A PDF whose table of contents loops no longer crashes the app, and a book that crashed while opening is no longer reopened at every launch.
- The library shows a PDF's real page count instead of its file size in kilobytes, and the page it shows for a PDF or comic is the one the reader is on.
- Cancelling the metadata scan no longer removes the books it was still reading.
- Opening a very long book no longer runs out of memory while building its chapter map.
- A word set in small caps at the start of a paragraph is no longer drawn as a drop cap.
- Tapping the widget for the book already open no longer closes and reopens it, or turns a landscape book back to portrait.
- On iPad, the reader's custom color picker opens in place at full height instead of closing itself the moment it appeared.

■ Localization
- All the new text is natively translated across all 18 supported languages.
