Usage of --profile requires -Z unstable-options

[smessmer]

Trying to run "cargo screeps build", I'm getting:

~/screeps (master) [1]> cargo screeps build
cargo_screeps::run: compiling...
error: usage of `--profile` requires `-Z unstable-options`
error: cargo-web build failed: build failed

Adding -Z unstable-options doesn't help either:

~/screeps (master) [1]> cargo +nightly -Z unstable-options screeps build
cargo_screeps::run: compiling...
error: usage of `--profile` requires `-Z unstable-options`
error: cargo-web build failed: build failed

When I add a .cargo/config.toml with

[unstable]
unstable-options = true

then the error message changes to:

~/screeps (master)> cargo screeps build
cargo_screeps::run: compiling...
error: conflicting usage of --profile=dev and --release
The `--release` flag is the same as `--profile=release`.
Remove one flag or the other to continue.
error: cargo-web build failed: build failed

It works if I remove the --release from https://github.com/rustyscreeps/cargo-screeps/blob/master/src/build.rs#L41, but I imagine that I'm getting a debug build then and I'd prefer a release build.

Also, I'm not actually getting a working debug build but I'm running into #29 then
