Multi-platform http server (#646)

- Add server support to `http-module`
- Ensure `DevelopmentService` works on all platforms (including posix)
- Ensure the built-in web server with dashboard works on all platforms (inluding posix). It still has some issues with certain featuers, but the basics work.
