* Small code optimization

* Add configuration flag SSH_EXPOSE_ANONYMOUS

If this flag (default True) is set to false, the SSH clone URL will only be exposed if the current user is signed in.

* Default SSH exposure set to false

To match GitHub and for security reasons, SSH URL exposure is disabled by default.
In addition to that. minor code changes have been applied.
