[kronolith] Kronolith / sabredav: No basic authentication headers found

[lst_hoe02 at kwsoft.de]

So i set $session_control = 'none' below the $serverType = 'Webdav' in  
rpc.php and it really solves the problem, our session counter is back  
to normal and all the CalDAV sessions are gone while it still is  
working as expected. Will this be included in later releases and can  
someone with more knowledge about internal workings have a look at it.  
It is a big win as soon as the number of CalDAV clients start raising.

Thanks

Andreas
