[Vobject] Reading nonstandard properties

There was discussion on the Calsify mailing list about what the URL 
property should be used for; I'd say it's not really clear what URL is 
really useful for.

Yup, dashes don't work for variables in Python.  Happily, RFC2445 allows 
'-' but not '_' in component names, Python allows '_' but not '-' in 
variable names, so vobject just converts calendar.vevent.x_link into the 
'x-link' property on a vevent.

Sincerely,
Jeffrey
