Fixes and create war file

Bonjour Arnaud,

Merci! For your excellent blog post http://blog.zenika.com/index.php?post/2013/01/21/using-thymeleaf-with-spring-mvc - I've found it so useful for learning Spring MVC.

Please find a fix and some updates to make it possible to create a deployable 'war' file.

Sorry for any bad use of 'French'.

Many thanks,

Gareth
