feature request: save countdown timer settings

[AdeleneDawner]

I primarily use this alarm clock to remind me to check on a game that can be interacted with every half hour, and it works well for that. But I turn the alarm off at night, of course, and it's a little annoying that I have to set it up again every morning when it's the exact same settings every time; I'd like to be able to save them, so that starting the timer up again in the morning only takes a couple clicks.
