Automation Trigger: CRON - Implemented

[arladmin]

A CRON option as a trigger would be a great addition.

Use-cases include running periodic audits, data-cleaning, report generation etc.

This is another great suggestion @arladmin and one we will get round to eventually. To be honest, I feel this is pretty essential and will push at the next roadmap meeting.
