also, fix indentation

After click on graphic and go back, the page is redirected to home instead of display the graphic again

User can reset the query with the search panel

With this, we will able to select the graphic we want and display. For now, we have only the select.

The rest is broken :)

* Render graphics in RJS without code
* Supporting the generation of bar graphics using domains
* Build graphics from listbox

The idea is get more information from listbox and make the script a bit smarter

We make it possible to define function the same way it's currently
possible to define accounts. The idea is similar: to be able to use this
information in accounting generation rules.

The typical accounting generation configuration using this will use the
function defined on the supply line if any is defined and with a fallback
to the function defined on business process' trade model path.

For now we don't introduce such configuration by default, but this may
become part of  the configuration generated by configurator some day.
