Shotnix 0.19.1-beta

Fixed

• The app crashed instantly on launch on every Mac except the machine it was built on (issue #25; present in all recent releases). A resource-bundle packaging bug made the startup sound lookup fail fatally — Shotnix now locates its resources correctly inside the app package and degrades gracefully if they're missing. The shortcuts library is patched against the identical crash in the Shortcuts preferences pane.
