 - property-term
 - property-create
 - item-merge

All tests have also been updated and rights / perm
checking code has been changed.
i18n for the messages has also been updated / removed
Example and default configs have also been changed

DEPLOYMENT NOTE: OAUTH permissions rights need to
be updated removing previous rights and instead including
item-term, property-term and item-merge
