Convert EMailFormatterExtension to an abstract class.

With the previous changes, all formatter extensions derive from
GObjectClass and implement the EMailFormatterExtensionInterface.

Simplify things further by making EMailFormatterExtension an abstract
base class so formatter extensions are now just direct subclasses and
need not bother with implementing GObject interfaces.
