* Add a better descrition for the `imagebox` role in the wiboxes system ;
* Improve image + code render and integration into the descrition ;
* Add a second code exemple to show both coding style (imperative and declarative).
I think the user can now have a better overview of what's a `wibox.widget.imagebox` and how to use it.
This allows to figure out if a test will generate an image without
having to run it. The long term plan for this is to run the tests during
compiling ("make") and not during configuring ("cmake"). Since the list
of files to e.g. install needs to be known during configuring, this
commit is a necessary step in that direction.

This uses DOC_HIDE magic in the actual test code, except for the
template.lua files which do not have it.
