2.2. TC CALDAV

Focused mainly on server-info-document DAV Server Information Object and we seem to be getting close to something that is fully baked. Format has been solid for a while. We now have a mechanism for the client to detect a change in the server-info-token via HTTP responses. Ken has uploaded his server capabilities spreadsheet for our GitHub repository as a staring point for accumulating this info from our members/vendors. During the next months the server-info document will be finalized. The TC will work on the server/client features matrix and integration with DEVGUIDE. The iCalendar-patch draft will be reviewed.
