Enabling WASI when building an instance sets up the default WASI imports, and can optionally capture stdout/stderr. I'd like to set up something similar for stdin, but Wasmer doesn't support that yet. I also improved error handling in WasmRuntime by adding Wasmer's last error to the thrown exceptions where appropriate.
