[fb] Honor the parent folder group permissions

When uploading files or creating folders, Hue does not seem to honor the parent folder's group permissions like HDFS does. For example, if I have a folder owned by "cconner:superuser" and I create a file/folder in there in hdfs, the group will be "superuser". However, when I do this in Hue, the group is "cconner". I looked in the config options and didn't see any way to change this behavior. I'm not sure if this is working as designed and should be a feature request. I'm filing as a bug to start with.
