[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.
The personal information describing a User can be modified using the edit form
of the user. You can access it through the dropdown-menu under the link on the
top-right of the window, labeled by your login. In this menu, click the
"profile" link to go to this form.
Each user can as well customize the site appearance using the "user's
preferences" link in this menu. This will show you a form to configure which
boxes are displayed, in which order, etc...
