Convert EMailParserExtension to an abstract class.

With the previous changes, all parser extensions derive from
GObjectClass and implement the EMailParserExtensionInterface.

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