bail!() no longer works with quicli 0.4

I think this is caused by https://github.com/rust-lang-nursery/failure/issues/258 and https://github.com/rust-lang-nursery/failure/issues/110, but I thought it worth mentioning, as I hit this upgrading from quicli 0.3 to 0.4.

I'm not sure there's anything that can be done in this crate though, so feel free to close if you want.

Reproduction:

Source

use quicli::prelude::*;

fn main() -> CliResult {
    bail!("This does not work!");
}

Reproduction

cargo new quicli_bail; cd quicli_bail
cargo install cargo-edit
cargo add quicli
echo -e 'use quicli::prelude::*;\n\nfn main() -> CliResult {\n    bail!("This does not work!");\n}' >src/main.rs
cargo build

Result:

   Compiling test_quicli v0.1.0 (/Users/gib/tmp/test_quicli)

because of changing returning type.

That type is from exitfailure
