Documentation: Draft of chapter about sessions

Hi,

Steven Costiou and I wrote a draft about session management.

I updated the online doc (http://doc.iliadproject.org) and the pdf
http://github.com/NicolasPetton/iliad/raw/master/doc/iliad.pdf

I will finish the chapter ASAP, and then start writing the chapter about
widgets.

Cheers,
Nico

very good, I did read the widgets and the sessions, and it's nice.
