title: how to get total file size of queue not single file size in plupload
body: <p>How can i get total number of files size which are in queue. I want to allow user to upload only 100 mb file so now if any one selects a file greater than 100mb this code works good but when i choose 2 files of 60-60 mb than total is 120 mb and this will not show any error. any idea for the same </p>
  
  <pre><code>$(function() {
      $("#uploader").plupload({
          runtimes : 'html5,flash,silverlight',
          url : 'http://&lt;?=$bucket?&gt;.s3.amazonaws.com/',
  
          multipart: true,
          multipart_params: {
              'key': '&lt;?=$filepath?&gt;${filename}', // use filename as a key
              'Filename': '${filename}', // adding this to keep consistency across the runtimes
              'acl': 'public-read',
              'Content-Type': 'application/octet-stream',
              'AWSAccessKeyId' : '&lt;?=$accessKeyId?&gt;',     
              'policy': '&lt;?=$policy?&gt;',
              'signature': '&lt;?=$signature?&gt;'
          },
  
          // optional, but better be specified directly
          file_data_name: 'file',
          filters : {
              // Maximum file size
              max_file_size : '100mb'
              // Specify what files to browse for
              //mime_types: [
              //  {title : "Image files", extensions : "jpg,jpeg"}
              //]
          },
