Title: Changed pygments to highlighter

Same change as in #28, but in one commit instead.

Pygment has been giving me this warning recently:
```
Deprecation: The 'pygments' configuration option has been renamed to 'highlighter'.
Please update your config file accordingly. The allowed values are 'rouge', 'pygments' or null.
```
