Add interactive list of templates to choose from to resolve #812

[dapplion]

🦅 Pull Request

Shows an interactive list of template options if no template positional argument is passed when calling create-aragon-app. Demo:

? Chose a template to scaffold from (Use arrow keys)
❯ Aragon bare boilerplate 
  Aragon React boilerplate 
  Your first Aragon app (tutorial) 

If silent = true, the template react is used requiring no interaction.
Also added the template options dynamically to the command documentation:

Create a new aragon application

Positionals:
  name      The application name (appname.aragonpm.eth)
  template  The template to scaffold from (bare, react, tutorial)

🚨 Test instructions

Run create-aragon-app without providing a template

Thanks @dapplion. I reviewed it and is working great and make things much user friendly 🎉

What you think if we take the opportunity to also add this #831 in case React or bare boilerplates are chosen?

@dapplion we can merge this one and work on a new PR for the extra changes
