When downloading a book via OPDS, a directory picker now lets the user choose the save location instead of always saving to the SD root. Each OPDS server has a configurable default download path (persisted in opds.json) that the picker opens to. Falls back to "/" if the saved path no longer exists on disk. - Add DirectoryPickerActivity (browse-only directory view with "Save Here") - Add PICKING_DIRECTORY state to OpdsBookBrowserActivity - Add downloadPath field to OpdsServer with JSON serialization - Add Download Path setting to OPDS server edit screen - Extract sortFileList() to StringUtils for shared use - Add i18n strings: STR_SAVE_HERE, STR_SELECT_FOLDER, STR_DOWNLOAD_PATH Made-with: Cursor
