v0.5.0 - trailing commas and spaces around operators

Issues #26 and #30 were implemented with pull requests #32 and #31 respectively. With these changes ECS will require:

• adding trailing commas in all multiline arrays and methods,
• adding spaces around almost all operators.

So:

        return $this->testParameters(
            "a"===$this->getValue()
        );

shoud be changed into:

        return $this->testParameters(
            "a" === $this->getValue(),
        );
