Attributes in deploy.rb

Hi my argentine friend,

Inploy failed to read de values in deploy.rb file when I used de syntax deploy.application = "app" instead of application = "app".

I used the file example in the READ of inploy github source page as base to my own deploy.rb.
It's working with "deploy." prefix, but I don't know if it's a my fault or inploy a issue.

Regards.
