Introduce new source discoverer

The new source discoverer is a complete overhaul of the current code. It is async-only, correctly threaded, and easier to maintain. A major new feature of this web source discoverer is that it now pings the server to see if the URL feeds us back with an iCalendar file. Furthermore, it continues to use E-D-S WebDAV discovery functions as a fallback mechanism. Fixes #380
