Fix for ng-file-upload - Create and segment invalids via an error blacklist. Do not mark files invalid because of maxLength.

ng-file-upload-fix.js

    function separateInvalids() {
      var skipErrors = [ "maxFiles" ];

      valids = [];
      invalids = [];

      angular.forEach(allNewFiles, function (file) {
        if (file.$error) {
          if ( skipErrors.indexOf( file.$error ) !== -1 ) return;
          invalids.push(file);
        } else {
          valids.push(file);
        }
      });
    }
