Classe EditorScene renommee en ElementScene. Ajout de la classe ElementView. Ajout de la classe ElementItemeditor, classe parente des widgets d'edition. Modification des classes relatives a l'editeur afin que toutes aient acces a l'editeur, a la scene et au QUndoStack. Tous les widgets d'edition heritent donc de ElementItemEditor. Ajout des methodes abstraites property() et setproperty() dans la classe CustomElementPart et de leur implementation dans les classes qui en derivent. Sont desormais annulables les modifications : de style, sur les arcs, sur les bornes, sur les ellipses, sur les cercles, sur les champs de texte, sur les textes et sur les lignes. git-svn-id: svn+ssh://svn.tuxfamily.org/svnroot/qet/qet/trunk@104 bfdf4180-ca20-0410-9c96-a3a8aa849046
