I have updated the beta version again.

Now I think the remaining problems are solved:
- If snooze time is selected to be one of the available choises in Clock application, it will correctly show there (so setting that attribute did in fact help, I must have tested it poorly previously)
- If snooze time is not set, a 10 minute snooze is used regardless of what the "platform default" is. As it seems platform default is not easily settable by user, this seemed like a reasonable compromise.
- Alarm scheduled by ProfileMatic can be disabled from clock application even if sound file is not specified.

I have tested the behaviour somewhat, but not extensively... so all interested please do test it to get it just right.
