radicale2: Update CalDAV/CardDAV server to v2.x

Radicale 2.x adds support for many new clients,
bug-fixes, etc so add v2 of this application.

We do it as a separate package for those not
ready to switch (it's not an straight inplace
upgrade from 1.x).

We do however CONFLICT with 1.x as they can't
be run side-by-side on the same host (without
containers for somesuch).

+The Radicale Project is a CalDAV (calendar) and CardDAV (contact) server. It aims to be a light solution, easy to use, easy to install, easy to configure. As a consequence, it requires few software dependances and is pre-configured to work out-of-the-box.
+
+The Radicale Project runs on most of the UNIX-like platforms (Linux, BSD, MacOS X) and Windows. It is known to work with Evolution, Lightning, iPhone and Android clients. It is free and open-source software, released under GPL version 3.
