Fix ember-cli deprecation warning

In ember-cli >= 2.12.0, the following deprecation warning is issued:

DEPRECATION: `ember-cli/ext/promise` is deprecated, use `rsvp` instead...

This release moves to using RSVP as instructed in the warning.

Thanks to @nelstrom for the patch!

Updated `agent` support

When specifying the agent option for your SSH connection, the ssh2 library requires privateKey to be unspecified. This release makes providing the privateKeyFile property optional, so that you can actually use the agent option.

Passphrase and Agent support

You can now pass the passphrase and agent options to this deploy plugin. Both of these will be passed directly to the SSH library (ssh2).

Tilde support for privateKeyFile

You can now use a tilde path when specifying the location of your privateKeyFile. Instead of /Users/username/.ssh/id_rsa you are free to use ~/.ssh/id_rsa.

Documentation Updates

This release contains no features or bug fixes, just some documentation updates to the README and field updates to package.json.

Initial Release

This is the initial release of ember-cli-deploy-ssh-index. With this release, you can follow the instructions in the README to deploy, list, and activate your Ember application's revisions on a remote host via SSH.
