SoundDeck v0.3.0

Applying a pack now really changes your Windows sounds. Until this release the apply screen only simulated the steps and nothing was written to the system — that is fixed, and it is the main reason to upgrade.
Every apply first saves the events it is about to change, so you can undo it from the Backups screen at any time. Backups are real files now and survive restarts and updates.
If anything fails partway through, everything already written is rolled back — you never end up stuck between two packs.
After applying, the settings are read back to confirm they landed, and any mismatch is reported instead of silently claiming success.
Only sound events that exist on your machine are touched. Nothing is created for programs you do not have installed.
Custom packs can now actually be applied. They previously kept only the file name and lost the path to your .wav files, which made them impossible to apply.
Pack audio is downloaded once and reused, so applying the same pack again does not re-download it.
New: a short tour the first time you open the app, and a summary of what changed after you update.
New: the app tells you in the header when a newer version is available.
As before, no administrator rights are needed, no system files are touched, and nothing is written outside your own user settings.
