forking folder should show progress

[gordonwoodhull]

This operation is very slow and nothing shows up until it's done.

Some kind of spinner or progress bar should be shown.

Not questioning the requirement for some UI feedback that something is happening, but has this process slowed since the tree refactoring?

Looks like the slowness here is GitHub-related. When I fork the same folder on old versus new RCloud on Research (with gist backend) it's only a couple of seconds, no difference that I can tell.

(That's a folder with only one notebook. A folder with eight notebooks takes more like eight seconds, which is long enough to make one wonder what is happening.)
