Title: [nemo-qml-plugin-contacts] Use vCard 3.0 when exporting contacts

vCard 3.0 was defined in 1998 and has much saner encoding behavior. Using 2.1 may be causing compatibility problems with some devices.

The other code I could find using QVersitContactExporter is using the default of 3.0 as well.
