Title: Bug 974554 - CalDAV parser should accept ical inside xml comments nested  in <calendar-data> elements r=millermedeiros

Yahoo! returns `` elements that look like

```
...
BEGIN:VCALENDAR
...

...
```

and right now we choke there since we're ignoring comments and expecting for things to look more like
```
...

BEGIN:VCALENDAR
...

...
```

But both are valid according to http://tools.ietf.org/html/rfc4791 9.6
