Default template for cry

[paulcsmith]

This lib looks nearly perfect fit for running quick commands and inspecting the app.

The one thing missing is some kind of "template" option so by default it can do something like require "src/app.cr". Is that just not documented yet?

If it is not in cry and you'd be ok with it, I can add an option so it will look for a .cry-template or something like that. What do you think?

Sorry. I've been swamped the last couple months. I'd be fine with that. Thanks.

@paulcsmith Did you ever add this in a fork that we could move back in?
