Title: WIP: clickable text

![excuse the halos around the fake mouse cursor, I was lazy] (http://img.ctrlv.in/img/52d5c8fe1c51f.png)

That's an actual tooltip, indicating the command that will be run when you click the line.
The page arrows are also clickable

Implementation is done using an HTML-like XML subset as an intermediate layer.
The language is parsed using jaxb and is described here:
