Merge remote-tracking branch 'refs/remotes/origin/master'
- Implemented update method for images in Media ManagerApiCore, to address the sent to trash operation from the REST API
- Splitted media_manager_api_server.js into media_manager_api_server.js and media_manager_api_server_CLI_launcher.js.
  This is to be able to call media_manager_api_server.js both from the command line and from the tests
