Rethink templating

I mentioned to @NMinhNguyen that I had a few misgiving when adding a templating feature.

1. Partly, the implementation is a little confusing right now due to the way we are piggy-backing on the installation of create-react-app. There are changes that create-react-app makes which are not part of its template and we then need to undo or amend. It’d be nicer if everything was just copied across from a single folder.

2. More substantively, a widget is dependent on an app, so if the configuration of an app and verson of modular installed doesn’t include support for TypeScript you should not be able to install a widget that depends on this. I’m not suggesting that we add validation – probably it means that the template for a widget is stored within the modular package (for now called modular-scripts). This was brought up by @threepointone a week or so ago, and I’m writing it down now for posterity.

3. Finally, there are now three templates (repo, app and widget). Currently, only app and widget are configurable, and we will likely want repo to be configurable, too. (If/when this is required, it might need to support something like wizards.)

Leaving this open for a bit, will close by the end of the week if no new info presents itself.

Ha, you were the one that asked for them originally! ;D

I’m also a big fan of changing my mind when presented with new information 😛

Yeah, let’s just remove the template arg for now (happy to do it myself too if you’d like, I could send it as soon as tonight)
