Offer zip builds

[ghost]

If you go here:

http://forge.rust-lang.org/other-installation-methods#standalone-installers

you see MSI and TAR.GZ installers for Windows. This is strange because typically
programming language vendors will offer:

1. MSI or EXE installer
2. ZIP file with compiler or interpreter that can be extracted and run

the Rust TAR.GZ is similar to option 2, but if you extract rustc.exe wont
actually run because even with the TAR.GZ it has to be extracted and installed
before rustc.exe is usuable. This contrasts with other programming languages that offer both an executable installer and ZIP files that can be extracted and run. For example Go:

https://golang.org/dl

and Nim:

https://nim-lang.org/install_windows.html

Python:

https://python.org/downloads/release/python-373

and C#:

https://dotnet.microsoft.com/download/dotnet-core/2.2

PHP:

https://windows.php.net/download

Perl:

This is primarily a packaging issue and should be posted to https://github.com/rust-lang/rust (like the other tickets) instead.

This repository should have a small issue tracking the others, so that we can do a change once the infrastructure is there.

Keeping open as a marker.

Unless we move that download page from the forge to the website (which would be a good thing) this issue should be on the forge.

Closing in favor of the forge issue as per previous comment.
