Enhancement: Add official support for being able to define "ssh_key" in Rakefile

Add official support for being able to define "ssh_key" in Rakefile. Not being able to define a specific SSH key for use in conjunction with ssh_user is kind of a pain.

SSH config files are great for this, you can tell SSH to use specific keys. You can do something like this in ~/.ssh/config:

Host heroku.personal
  HostName heroku.com
  IdentityFile ~/.ssh/identity.heroku.personal
  IdentitiesOnly yes

Totally spaced on this. I suppose I could define a custom ssh config for octopress.deploy and specify the key and then just specify in the Rakefile to use that host instead. I'll give this a shot. Thanks.
