[Remind-Fans] Remind CalDAV adapter release

[Jochen Sprickerhof]

Hi,

I've just pushed the first version of my Remind CalDAV adapter to
Github:
           https://github.com/jspricke/Radicale/

I've used the Radicale CalDAV server as a base and added a special
storage adapter to translate between the remind and iCalendar syntax.
What's working:
- Two way sync between CalDAV and remind (tested using the aCal app on
  Android resp. sync into the Android calendar using the CalDAV Sync
  Adapter).
- Initial support for a standalone mode to convert from Remind to ics
  (rem2ics.pl replacement).

Please not that this is tied to a Abook adapter at the moment, so you
need to set up a fake file for that adapter as well, if you don't use
Abook. Patches to disentangle this welcome!

Have Fun

Jochen
