/**
* Objet FormValidator
*
* Permet de g?rer la validation de formulaire
*
* Mettre onsubmit="return formValidator.check(this);" dans la balise <form>
*
* en dessous de </form>, mettre :
* <script type='text/javascript'>
* 	formValidator.addRules("id_du_champ","contraintes");
* </script>
*
* contraintes est une liste avec l'espace comme separateur
* les valeurs peuvent etre :
*		champ obligatoire 	=> required (marche aussi pour le select)
*		taille mini			=> minlength=X
*		taille maxi 		=> maxlength=X
*		champ numerique		=> numeric
*		nombre de decimales => decimals=X
*
*		pour les checkbox :
*			formValidator.addRules("Checkbox","minlength=3 maxlength=4 baseid=meschecks insertafter=id");
*
*			TOUT LE TEMPS METTRE "Checkbox" au lieu de l'id
*				minlength	=> nombre minimum de cases devant etres coch?es, si pas pr?cis?, les cases sont optionnelles
*				maxlength	=> nombre maximum de cases devant etres coch?es, si pas pr?cis?, pas de maxi
*				baseid		=> base de l'id des input
*				insertafter	=> id de l'?l?ment apres lequel on veut mettre le rapport d'erreur, si pas pr?cis?, apres la derniere check
*				newline		=> y ou n indique si le rapport d'erreur se met sur une nouvelle ligne. Si pas pr?cis?, n
*
* ne pas mettre d 'espace entre = et la valeur
* decimals peut etre mis a 0 pour un entier
*
* Exemple : formValidator.addRules("Description","maxlength=3 minlength=1 required");
*
* <script>
