formatter: Serialize Transition border and invert properties

Browse source 
Marking them as children properties and properly allow serializing
clips children properties.

This doesn't handle several TrackElement of a same type with
different property values but this require more worked already
marked as fixme to allow specifying full path of elements in the
children properties API.
