Added support for an ssh port

[chip]

Hi,

My server doesn't respond to port 22, so I needed to add support for the ssh port. Please feel free to merge this in if you feel there's a need for your users.

Thanks,
Chip

Hi Chip! There are 3 ways to handle this that I can think of. One is adding the ssh_port, as you have done. The second is doing it similar to rake-remote_task and have a ssh_flags to specify arbitrary ssh options. That way, we don't just support the port, but any other ssh option the user may need. Lastly, we can decide not to handle this in Mina, and make people handle this in their .ssh/config files.

Personally I think people should update their .ssh/config files instead. But this may be the wrong approach.

@rstacruz, what's your take on this?

Thanks!

You can do this with set :ssh_options, '-p 22'.

Let's add :port on the next release.

Also, I think it's best that Mina not be opinionated about how users manage their own SSH config files.

On an off-tangent, I'm also thinking of a convenience setting :uri where you can define user/domain/port/deploy_to using :uri, user@domain:22:/var/www/foo.com -- would be cool for multiple servers.
