automate prompts

[nkovacs]

I'd like to automate the generation of templates, e.g. I'd like to be able to do something like this:

vue init webpack my-project --name "Foo" --description "A vue.js project" --author "Me" --build runtime --no-router --lint --lint-config airbnb --unit --e2e

This would make it possible to automatically test templates, e.g. generate with --lintConfig airbnb, then run eslint on the generated template, then do the same with --lintConfig standard etc.
