Patch Set 6: Looks good to me, but someone else must approve

I have 2 points:

- It would be nice if the cloned repository were added to the Repositories View automatically
- Choosing a different username for the clone operation would also be nice. If i export a Team project set, all repository urls contain my username for the repositories (since we have no anonymous access). So everybody have to edit the psf-file manually and add their usernames.
