Release build as default

[sourcebox]

When just running cargo bundle, a debug build is used, so you have to run cargo bundle --release for a release build. IMO this should be the default, because bundles is normally used for distribution and debug builds are kind of rare in this situation.

I disagree, I think it should match cargo build as it does now, for consistency - otherwise I'll have to learn a --debug flag when I want to test my application as a bundle.

Though the documentation could spell out more explicitly that --release is needed.

On the other hand, I use cargo-wix to create the Windows installer and this will always use a release build without any flags.

cargo install also use --release as default

I'll retract my earlier statement, I now agree that this should default to a release build, like cargo install.
