[FEATURE] auto dismiss

[Xnyle]

Would be nice to have the option to auto dismiss an alarm after given time.

Use case is: Want to get reminded every day at a certain time, but if I don't react within a minute, alarm should stop to terrorize everyone else ;-)

yes. i had a morning alarm with an internet stream going on. i didn't wake up to close it and it just ran and ran until the phone got hot and the battery died.
