Added the vikingo-rails-config.rb file

This is what the template does for now:

  * Removes the **log/** directory
  * Removes the **tmp/** directory
  * Removes the **README.rdoc** file
  * Removes the **.gitignore** file
  * Creates a file which contains the secret token
  * Modifies the **config/initializers/secret_token.rb** file to read the token
  * Modifies the **Gemfile** lines containing sass-rails and coffee-rails
  * Copies a new .gitignore file for the project
  * Initializes a new git project
  * Adds all the files required
  * Creates the first commit
  * Creates the heroku instance and configures secret token
Modified the Gemfile
