title: grunt-init template conditional prompts
body: <p>I'm creating a new <a href="https://github.com/gruntjs/grunt-init" rel="nofollow">grunt-init</a> template for my project and was wondering if there is a way to do conditional prompts based on the answers given to previous prompts.</p>
  
  <p>My main goal is to be able to use the Github API to create an issue when I create a new module in my project. After asking for the module information, I would ask if a Github issue should be created. If yes, then ask for information like assignee, milestone, labels. If no, I don't care about any of those features.</p>
  
  <p>Right now, I can just default them to blanks, but I'd like to just skip those prompts entirely.</p>
