Proper export/import of the ting_reference relation

After upgrading Relation from beta1 to 7.x-1.0-rc3 it doesn't seem
nescessary to save the ting_reference relation by hand in
ting_reference_enable(), and will break because relation_init() no
longer exists. So I replaced it with a proper feature export/import in
ting_reference.relation_type_default.inc.
Updated makefile to use relation rc3
Merge pull request #1 from ding2tal/relation-feature-export-not-by-hand
