* Fixed indentation

* Added test coverage for JSON.GET command

* Changed module version resolving using annotations mapping

* Re-written CommandResolver test

* Update ClientInterface.php

* Changes to CI, readme, removed unused modules from configuration

* Fixed build badge URL

* Refactored annotation check to be generic for each module
