A lot of work has been done here

Mainly, we have coded a rake task to install the gem and link it to the main website.

Calling this rake like this:

    rake captain:install[<PUBLIC_TOKEN_HERE>]

will install and activate your application online.

Also, I changed the name of the gem from 'deployd' to 'captain-rails' so that is more related to the main site and brand.

Fixed a small issue which was not signed on github.
