Summernote insertion of an image or a link to a pdf file

[pibrom]

Short description of what this feature will allow to do: update summernote getFileCallback behavior in order to insert a link to a pdf file if mime type is 'application' or, default behaviour, insert image if mime type is 'image'

Example of how to use this feature here is the update I've made on file helios-ag/fm-elfinder-bundle/src/Resources/views/Elfinder :

getFileCallback : function(files, fm) {
                if(files.mime.match('application')){
                    window.opener.$('.summernote').summernote('createLink', {
                        text: files.name,
                        url: files.url,
                        newWindow: true
                    });
                    window.close();
                }
                if(files.mime.match('image')){
                    window.opener.$('.summernote').summernote('editor.insertImage',files.url);
                    window.close();
                }
            }
