[dev] icalendar event generation patch

[Mike Cochrane]

linebreaks shouldn't be removed, they should be encoded. 
I just has a quick look at the RFC, here's a patch to try and see if it fixes
things. I'll leave it to someone else to commit this if it works. Line folding
needs to be added in this bit too.
