LPS-34218

Hey Marcellus,

this is the pull with my changes regarding calendar. I added the counting of resources and deletion export (at least as much as we have of this on trunk currently) and made some slight changes. I found a bug prevented me to test deletion, the CLSI.deleteCalendar#105 always throws exception, but I do not really know how should calendar "default" work so I did not fix it. However it seems to me this is not staging related and prevent site deletion as well.

Sometimes to add a calendar booking also not worked, but it might related to my browser (Chrome). And I also can't really test the notification templates, and I found the original portlet data handler did not have methods for it, so maybe it is not necessary, but I did not want to remove it until you check the pull.

thanks,
Daniel
