Addresses #170.

It might be better to use phpqa.extensions just like in the other tools. The extensions are already documented and you don't have to define extensions twice. What do you think?

$phpcpdNames = array_map(
    function ($extension) {
        return "*.{$extension}";
    },
    explode(',', $this->config->csv('phpqa.extensions'))
);
// ...
names' => implode(',', $phpcpdNames),

Good point. Refactored.
