[Vobject] Subversion move, vCard groups

[Jeffrey Harris]

Hi Folks,

Thanks to Lars for his patch.  I've added vCard group support to vobject
as of revision 109.  Please note that vobject's Subversion repository
has moved to http://svn.osafoundation.org/vobject/trunk/

Unfortunately you can't just do an svn switch to move existing
repositories over, I'm not exactly sure why, but it's not working.
You'll have to grab a new checkout.

In addition to parsing groups, I added serialization of groups and
validation tests so that iCalendar streams don't accept groups.

Sincerely,
Jeffrey
