Added rclone special remote, which can be used without needing to install
the git-annex-remote-rclone program. This needs a new version of rclone,
which supports "rclone gitannex".
This is implemented as a variant of an external special remote, that
runs "rclone gitannex" instead of the usual git-annex-remote- command.
Parameterized Remote.External to support that.

In several cases, there's an old, maybe unmaintained special remote,
and rclone also supports the service. I don't know which is better,
so I added tips pages for these, listing both possibilies, so users can
fill in the details.
Added some things listed in special_remotes/rclone that were not
in the cloud provider list, so users will see it supports those.
But, omitted S3 and webdav, since it's probably better for users to use
what's built into git-annex than going via rclone.
The rclone list is out of date apparently, as rclone.org has more,
so I added a note at the bottom for users to check.
