CLI status should support --untracked-files

A special options handler is added to properly handle the short -u alias
of the option.

The "normal" mode is not supported by this patch, because this mode of
listing untracked files is not
supported by the org.eclipse.jgit.lib.IndexDiff class. This mode is not
necessary for my use case. It can be added later if anyone really needs
it.

The StatusTest is updated to cover all possible combinations of the
--porcelain and --untracked-files options.
