Support for extra tokens in OAuth response
Added support for making extra tokens in OAuth response, available as a property

Certain OAuth service providers, provide extra information in
the form of additional tokens that are returned as aprt of a
successful OAuth exchange.

These additional tokens are made available as a read-only
property. The property's type is QMap<QString, QString>.

Changed the extraTokens property to QVariantMap
Changed the extraTokens property in O1 & O2 to be a
QVariantMap to make it accessible in a QML context. The
existing QMap<QString, QString> was not accessible in QML.
