Extra dope! So much work, really good to see it come together.

Dope dope dope! Massive chunk. We should make sure that for all conversations that are left for the future we have follow-up issues.

Also I find it strange that we have a dedicated light-node bin in the light-node crate, can't we just use the main main?

I was planning to go through each comment and capture everything (that's not yet addressed) in a followup issue after this gets merged. Ok?

That's the way absicca generates the create structure on init. e.g. running abscissa new test-app yields:

tree                                                                                                                                                                                
.
`-- test-app
    |-- Cargo.lock
    |-- Cargo.toml
    |-- README.md
    |-- src
    |   |-- application.rs
    |   |-- bin
    |   |   `-- test_app
    |   |       `-- main.rs
    |   |-- commands
    |   |   |-- start.rs
    |   |   `-- version.rs
    |   |-- commands.rs
    |   |-- config.rs
    |   |-- error.rs
    |   |-- lib.rs
    |   `-- prelude.rs
    `-- tests
        `-- acceptance.rs

@tarcieri can you provide some input on the rationale here?

Great job @liamsi! Only have a few comments/questions inline, but looks great otherwise :)
