Books on Map Forever

## v1.0.3

### New: Optimized route
- New **Optimized route** button in the options window (or `/bom route`) builds a route through every book you haven't collected yet.
- Books are ordered by set: Starting set first, then Level 35, 45 and 60.
- Within each set, the path is optimized from your current position (nearest book first, then refined to remove detours), and each continent is finished before you switch.
- Books available in two places (e.g. Rumi of Gnomeregan) use whichever spot fits the route best.
- The route recalculates automatically when a book is collected.

### Route tracker
- Small movable window showing the next book: icon, location, coordinates, distance and a direction arrow.
- Buttons: **Skip** (skip a book for this session), **Recalc** (rebuild from your current position), **TomTom** (send the whole route as numbered waypoints), **X** (close).

### World map
- Book icons show their step number in the route.
- Blue lines connect the route steps on zone and continent maps.
- The pin tooltip shows the route step.

### Commands
- `/bom route` – toggle the optimized route
- `/bom route list` – print the route in chat
- `/bom route tomtom` – send the route to TomTom

### Interface
- The addon version is now shown next to the title in the options window.
- The language selector moved to the top right of the options window.
- French translation for all new texts.
