First commit version with comments
Second commit for the version with comments
Display comments about a proposition

TODO: How to prevent from having a security failure while displaying the content since the user can write html code ?
Removed "comments" from the Proposition class
Modification of CommentHandler.php : no need to persist the proposition
Added HTMLPurifierBundle to filter the output of the wysiwyg editor
Comment in commentForm.html.twig : TODO: wrong place for the error message of the editor field
Added comments in some views. Be careful with the filters used in the templates.

TODO: 	Now the command "php app/console cache:clear" returns an error since it does not have the permission to remove some files
	created by the HtmlPurifierBundle.
	Can use "sudo php ..." instead...
	The command 'setfacl' does not seem to work
	See ACLs...
Upgrade TinyMce to version 0.3.xxx

TODO:	Be careful that the input textarea should be at the same adress than where is displayed the output
	Because we do not respect that the routes for the smileys are wrong and it is like they vanish
	So put the input form at the same adress than the output
The modification of a proposition now takes place directly in the content page
Modification of the layout title
Erasure of the template for modifying a proposition
Bug correction : validation of the form of a proposition
