Add the dev commands into new project README

[Frozenlock]

I find myself returning to old project without knowing which command was acceptable. (lein figwheel vs lein figwheel devcards, how to start a repl, compiling less files...)

I can check reagent-template's readme, but I'm afraid one day the old projects won't be compatible with some new commands. Then it will be a game of "guess what was the development tool back then".

I think injecting the development mode section into new readme (which is empty anyway) would help to make projects future-proof.

Thoughts?

Yeah, that might not be a bad idea. Would probably also make sense to add a changelog and maybe add something like :reagent-template-version key to project.clj that's generated. That way you could see what version of the template the project was made with and check the changelog.
