object name with slashes can not be listed

In swift's docs (http://docs.openstack.org/trunk/openstack-object-storage/developer/content/pseudo-hierarchical-folders-directories.html), it actually says that you must create 0-byte objects with type "application/directory" if you intend to use the pseudo-folder feature:

"To take advantage of this feature, the directory marker objects must also be created to represent the appropriate directories. The following additional objects need to be created. A good convention would be to create these as zero- or one-byte files with a Content-Type of application/directory."

So that's how we implemented things in Horizon; to expect those pseudo-folder objects and use those to allow traversal down into a structure. Unfortunately that doesn't play so nice with the *other* method of handling pseudo-folders which is basically to not use the "delimiter" argument on the API and just show everything, slashes and all.

At present I'm not aware of a good compromise between the two, so we erred on the side of the recommended practice in swift's docs. Suggestions are welcome.

We could make the FOLDER_DELIMETER configurable so that the pseudo-folder feature in swift could be optionally disabled if desired... https://github.com/openstack/horizon/blob/master/horizon/api/swift.py#L33
