UploadItem with HTML accept attribute

[janusz]

Hi,

Could you add to UploadItem possibility to set HTML attribute accept to filter types of files that can be uploaded?

https://developer.mozilla.org/en-US/docs/HTML/Element/Input#attr-accept

I have made a small workaround using overloaded getElementStyleHTML:

isc.UploadItem.addProperties({
    getElementStyleHTML: function() {
      var result = this.Super("getElementStyleHTML", arguments);
      if(this.accept) {
	result += ' accept="' + this.accept + '"';
      }
      return result;
    }
  });

We've added support for this to FileItem and UploadItem and the changes will hit nightly builds of 8.3p and 9.0d from April 20
