  29  *   Le code original de markitup 1.1.8
  30  *   a ete modifie pour prendre en compte
  31  *
  32  *   1) la langue utilisee dans les textarea :
  33  *              - si un textarea possede un attribut lang='xx' alors
  34  *        markitup n'affichera que les icones qui correspondent a cette langue
  35  *              - on peut passer une valeur de langue par defaut a markitup (le textarea peut ne pas en definir)
  36  *        .markitup(set_spip,{lang:'fr'});
  37  *              - une option supplementaire optionnelle 'lang' est introduite dans les parametres
  38  *        des boutons (markupset), par exemple : lang:['fr','es','en']
  39  *              - si un bouton n'a pas ce parametre, l'icone s'affiche
  40  *        quelque soit la langue designee dans le textarea ou les parametres de markitup ;
  41  *        sinon, il faut que la langue soit contenue dedans pour que l'icone s'affiche.
  42  *   2) les control + shift (ou alt) + click bouton qui ne semblaient pas fonctionner
  43  *      en tout cas sous FF3/ubintu/jquery 1.2.6 a verifier chez les autres (opera 9.5/ubuntu ok)
  44  *   3) gerer des types de selections differentes :
  45  *              - normales comme dans markitup (rien a faire)
  46  *              - 'selectionType':'word' : aux mots le plus proche si pas de selection (sinon la selection)
  47  *              - 'selectionType':'line' : aux lignes les plus proches
  48  *              - and 'return' : ugly hack to generate list (and so on) on key 'return' press
  49  *   4) forcer des actions multilignes sans avoir besoin de faire control+click
  50  *              - 'forceMultiline':true  : force donc une insertion multiligne
  51  *   5) correction de la recuperation des selections d'Opera et de IE
  52  *              en utilisant une autre fonction de split() qui corrige leurs bugs.
  53  *              (caretOffset n'est plus necessaire)
  54  *
