Alert dismissable

Added two new errors:

E033- `.alert` with dismiss button must have class `.alert-dismissible`
E034- alert dismiss button must be the first element in `.alert`
What should I do about ..

```
if ($('.alert .close').length && $('.alert').contents().eq(0).text().trim() !== '') {
            reporter('alert dismiss button must be the first element in `.alert`');
        }
```

Pass in the alert element?
