NovelNotifier 1.2.2

Fixed

• "Back up library" crashed (0-byte zip) for anyone who had chosen a theme — the backup snapshot mis-read the newer theme/notification prefs as string-sets. Regression-tested now.

From 1.2.1 (still applies to upgraders from ≤1.2)

• The app is now signed with a proper release key. Installs from v1.2 or earlier need a one-time uninstall/reinstall: back up library → uninstall → install → restore from backup → log in.
