Support more naming patterns for detecting twig templates

Currently such templates aren't detected as templates

``` php
        $stepsViews = array(
           1 => 'MissGirlsBundle:GirlManagement:steps/step1.html.twig',
           2 => 'MissGirlsBundle:GirlManagement:steps/step2.html.twig',
           3 => 'MissGirlsBundle:GirlManagement:steps/step_finish.html.twig',
        );
```
