There should also be a 'duplicity list-backends' that will show available backends and their protocol strings, something like:
ftpbackend    ftp://
sshbackend   ssh:// scp://
...and so on...

-- 
Backend imports should be made optional

Bug description:
Certain backends require other modules, ncftp for FTP, sftp for SSH, etc..  If the user is not going to be using these modules, it should not be a requirement to have them on the system.  I propose that we surround all backend imports with a try/except and that all modules should check requirements at import time prior to calling register_backend.  If a backend fails to load, the default should be silence, however a verbosity of INFO or better should show why.
