Windows API documentation for Rust

This is an experimental documentation generator for the Rust for Windows project. The documentation is published here:

https://microsoft.github.io/windows-docs-rs/

It can be manually generated (using the nightly toolchain) as follows:

1. Delete everything in windows-docs-rs/docs except: index.html, header.html, .nojekyll, and opensearch.xml.

2. Run the following command from the windows-rs directory:

PowerShell:

PS C:\git\windows-rs> cargo --config "build.rustdocflags = [`"--html-in-header`", `"d:\\git\\windows-docs-rs\\docs\\header.html`"]" doc -p windows --all-features --no-deps --target-dir d:\git\windows-docs-rs\docs

Cmd:

C:\git\windows-rs> cargo --config "build.rustdocflags = [""--html-in-header"", ""d:\\git\\windows-docs-rs\\docs\\header.html""]" doc -p windows --all-features --no-deps --target-dir d:\git\windows-docs-rs\docs

3. Delete everything in windows-docs-rs/docs except index.html, header.html, .nojekyll, opensearch.xml, and doc

4. Run git add . followed by git commit -am "<next version>"
