0.4.1

This a pre-release version of Azure Functions for Rust.

Important changes:

• Update dependencies.
• Fix Dockerfile template for cargo func new-app.
• Fix samples and documentation.
• Fix Ctrl-C handling (worker now ignores SIGINT).

The project is still very much a work-in-progress and none of the API will be stable until a 1.0.0 release is declared.

For now, the patch level will be used for implementing new features. When a minor version changes, it will indicate that enough work went in to signal getting closer to a 1.0.0 release.

Once 1.0.0 is hit, semantic versioning will be respected.
