Feature request: timer alert functionality + notification sound + snooze

[ghost]

Currently thyme only provides a stopwatch functionality, but there is no way to set a configurable timer alert e.g. for 5 minutes, i.e. the classic "Tea" or "Nap" functionality.

Feature Proposal

• Add a new menu option Alert which will have a submenu with preset alert timeouts, i.e.: 1min, 2min, 3min, 5min, 10min, 20min, 30min, 1hour.

Once the alert time elapses a notification popup box appears, with an optional sound configured in the alert settings. The alert would contain buttons to snooze or discard. Snooze duration can be configurable from the popup, and if the value is not explicitly set for e.g. 10 seconds, then the default snooze duration will be used (configured in the alert preset). (Just for reference, similar functionality is implemented in the android app called alarm clock plus which I found to be very handy).

Each alert preset will be configurable, i.e. it should be possible to add/remove/edit them, set a per-alert notification sound, as well as snooze duration. Saving an alert preset as default for new presets would also be handy.
