Title: Added reference to The book of OpenLayers3

I added a reference to the book in the "Lean" section, at first place and occupying half page, leaving space for future books.

If it is too ostensive let me know and I will place at bottom but I made this way because for the moment there are not much documentation of the project (API apart).

Cheers.
