[dev] Putting Escalation statuses into the ticket history

Hello, I'm currently looking for a elegant way to keep track of the different escalations a ticket had been through. To my understanding, the elements currently in the ticket_history_type table from from 41 to 49 are destined to do so. As per ./scripts/test/Event/Escalations.t, lines 256 and following, it also seems that they aren't implemented yet. Can you give me any feedback on this subject? Does anyone knows when the function is planned to be released? If not how may I contribute? Cheers, Philippe-Arnaud
