Title: Feature: haml coffee option

Adds the option to specify haml-coffee as the language compiler through `hamlPreprocessor` options:
```js
// karma.conf.js
module.exports = function(config) {
config.set({
...
hamlPreprocessor: {
options: {
language: 'coffee'
}
}
});
};
```

The default behaviour is unchanged, thus backward compatible.
