cAPI Core v1.2.7 nearing release.

After fielding some requests from a few subscribers, cAPI v1.2.7 has been updated to improve the functionality of certain Joomla content methods.

Additional work has been done to clean up inline Doctrine annotation for the Swagger API documentation. Since the move to inline API documentation (facilitated by the Zircote/Swagger) quite a few errors were introduced into the swagger.json for cAPI. After additional research and careful scanning of the Doctrine doc-blocks it looks like ALL errors have been resolved and the Swagger definition is finally validating again!
