Add "jgit clone" to support cloning off URLs that are JGit specific
The amazon-s3:// protocol is unique to JGit, and is not supported
by any other Git implementation. The easiest way to clone off of
one of those URLs is to use "jgit clone". This program also acts
as a simple example for any IDE developers who want to implement
a clone feature, as it is the minimum effort required to make a
user reasonably happy with the resulting repository.
