We changed the syntax from <z:link/> to <r:link/> to better reflect the fact that we want to render a link.

This makes it more intuitive to read zafu code, just replace <r: with ‘render’.

We also implemented some zafu shortcuts :

render version title:
<p do='[v_title]'>blah blah</p>

render the version text with zazen:
<div do='{v_text}'>some text</div>
