Edward Hervey 3912245f87 GESTrackObject: Add create_element vmethod
API: GESTrackObjectClass::gnlobject_factorytype
API: GESTrackObjectClass::create_element

Most track objects are only specific by the contents of the gnlobject,
therefore move the 'create_element' vmethod which was already present
in some subclasses to the top-level class.

Also make the code more robust
