Prototype an online-accounts module.
Integrates with the GNOME Online Accounts service. Creates Evolution sources for a GOA Google account and keeps them synchronized. Also registers a new CamelSaslXOAuth class for use with GMail. Authentication of Google Calendars and Google Contacts using OAuth is still under development.
