[kronolith] Handling of VALARM in Kronolith

[lst_hoe02 at kwsoft.de]

Hello

up until now Kronolith does not handle VALARM import as it is used by  
iCal Standard RFC 2445. I like to create a patch to get it working but  
have some questions about the way to go.

1.) Is it rigth that i have to extend lib/iCalendar/valarm.php first  
to get all desired functionality maybe with vevent.php as blueprint?

2.) To get Kronolith working with VALARM it is sufficient to extend  
kronolith/lib/Driver.php to use the iCalendar extension from 1.

Thanks for any pointer

Andreas
