The inspect_all function has been changed to Utils::inspectAll. (#178)

* Update CacheMiddleware.php

The inspect_all function has been replaced with a Utils::inspect_all function due to "mitigate problems with functions conflicting between global and local copies of the package".

* Update CacheMiddleware.php

The name of the new function is inspectAll and not inspect_all...

* Update composer.json

* Update composer.json

Make promises accept both version 1.4 or 2.0.
