  /*
   *   Le code original de markitup 1.1.15
   *   a ete modifie pour prendre en compte
   * 
   *   1) la langue utilisee dans les textarea :
   * 		- si un textarea possede un attribut lang='xx' alors
   *   	  markitup n'affichera que les icones qui correspondent a cette langue
   * 		- on peut passer une valeur de langue par defaut a markitup (le textarea peut ne pas en definir)
   *   	  .markitup(set_spip,{lang:'fr'});
   * 		- une option supplementaire optionnelle 'lang' est introduite dans les parametres 
   *   	  des boutons (markupset), par exemple : lang:['fr','es','en']
   * 		- si un bouton n'a pas ce parametre, l'icone s'affiche 
   *   	  quelque soit la langue designee dans le textarea ou les parametres de markitup ;
   *   	  sinon, il faut que la langue soit contenue dedans pour que l'icone s'affiche.
  
   *   2) gerer des types de selections differentes : 
   * 		- normales comme dans markitup (rien a faire)
   * 		- 'selectionType':'word' : aux mots le plus proche si pas de selection (sinon la selection)
   * 		- 'selectionType':'line' : aux lignes les plus proches
   * 		- and 'return' : ugly hack to generate list (and so on) on key 'return' press
   *
   *   3) eviter a Opera de gerer les evenements apres tabulation ou entree...
   *      il ne sait pas gerer (v11.51)
   * 
   *   4) ajout d'un <em> supplémentaire sur le html des boutons de la barre d'outil, pour des histoires de sprites
