Use cron for more flexible alarm schedules
Alarm Clock should use the users crontab for more flexible alarm schedules as well as robustness.
Would also allow for triggering alarms even when the applet is not running. This is is a big plus.
I'm not sure this is such a good idea anymore. Alarm Clock is a desktop application and shouldn't rely on any system cron job. Furthermore using the users personal crontab will clutter it up...
