[ctxcomponents] RQLCtxComponent: refactor init_rendering/render_body to ease overriding
init_rendering now simply execute the query to get result set to be displayed,
and store it in .cw_rset attribute.
Links to be displayed by default are now computed in render_body.
So you may now simply customise what to be displayed by overriding render_body.
Once you have read the `RQL tutorial`_ and you know the application'`schema`_,
you're ready to define your own views. Just type the RQL query retreiving data
you're interested in in the search field. If the view used to display them
doesn't fit your need, choose another one in the possible views box (this box
isn't displayed by default, but you can activate it in your `user
preferences`_). Once you're satified, add a `bookmark`_ if you want to reuse
this view later.
.. _`RQL tutorial`: doc/tut_rql
.. _`schema`: schema
.. _`user preferences`: myprefs
.. _`bookmark`: doc/bookmarks
Below are some example of what can be acheived...
.. winclude:: custom_view_last_update
.. winclude:: custom_view_rss
