api 7.x-1.13

Changes since version 7.x-1.12

Bug fixes

* Autocomplete for projects was not working. URL was changed from api/project/autocomplete to api-project-autocomplete and forms within the API module were updated. Issue: #2620478: Autocomplete in api_project_form always alerts 404
* Some "See all..." links were broken within reference sections like "22 functions reference this class". Issue: #2604938: Several see all links are broken for reference sections
* Links to inherited class members were not being made, such as Node::load(), which is really Entity::load(). Issue: #2656976: Links to inherited class members are not made
* Performance: Sped up the "shutdown" function that runs at the end of a cron run. Issue: #2514652: Shutdown is slow
