Fixed the regex in hackislyParseRegexTemplates()

If you want to organize your twig files in your theme with folders, something like this : 
```
theme/
  default/
    css/
    js/
    views/
      components/
        menu.twig
        header.twig
        footer.twig
    index.twig
```

The list of templates used in the debug bar will be broken :

Because the regex doesn't handle the case where the template name can use folders.

This one works with the regex : 
```
{% include 'footer.twig' %}
```

This one is retrieved twice with the regex : 
```
{% include 'components/footer.twig' %}
```

I updated the regex in hackislyParseRegexTemplates($obj) and now the result in the debug bar looks like this, I think it's also more practical to know exactly which file has been used.

If you don't use folders, you will now have : 
`/theme/<my theme>/<file name>.twig` instead of `<my theme>/<file name>.twig`
