Typescript & Javascript prompt for cycle-scripts about create-cycle-app

I think the way it is in #105 is quite good. I don't see big tradeoffs. We use native ES6 templates that allow us to reduce code doublication and therefore a source of possible mistakes. Webpack blocks makes this aproach feasable.
I would however move from the custom build/start scripts to just spawing the webpack cli, as this allows us to completely remove traces of the flavor on eject and not litter the working directory with scripts. (we could add this later on, as this doesnt matter pre-eject)
I think the init question should be part of the flavor, not part of CCA, because they are only used by the flavor.
