Expected Behavior

When setting the status in SuiteCRM, that status should be reflected in the iCal client

Actual Behavior

Status is not set in the iCal feed.

Steps to Reproduce

1. Configure iCal feed in SuiteCRM with publish key, configure iCal client (such as Mozilla Thunderbird) to sync the feed.
2. Create a meeting in SuiteCRM, save the meeting
3. Edit the meeting, set "Status" to "Cancelled"
4. Sync the iCal client
5. Observe that the event status has not changed in the iCal client application.

Context

We use the meetings function to coordinate field staff, which have been accidentally arriving at cancelled appointments, because the calendar app on their phone doesn't properly show that the appointment has been cancelled.
