Tracking v0.1.2

Hey @jonschlinkert and @doowb I wanted to let you know I made a few changes to the generator: 

1. There is now a question prompting if you would like to use gulp v grunt. 
2. gulpfile uses verb, but gruntfile still uses the old grunt-readme task.
3. User is prompted if they would like to use Bower or not. (I am confused as to why a helper really needs this, so maybe explain if I am missing something.)
4. User is prompted is they would like an `.editorconfig` file or not.

I also made a few minor changes the the README file.
can you change this template to `{%= include("author") %}`?
