Subject: [PATCH 1/2] Added target arch support

Previously electron-prebuilt would download the prebuilt binaries
for the architecture native to the platform. However there are
cases where being able to download for another architecture is
favourable.
This patch adds support for setting the architecture through
npm's --arch= parameter. (Issue #53)

 If you need to use an HTTP proxy you can [set these environment variables](https://github.com/request/request/tree/f0c4ec061141051988d1216c24936ad2e7d5c45d#controlling-proxy-behaviour-using-environment-variables)
 
+If you want to change the architecture that is downloaded (e.g., `ia32` on an `x64` machine), you can use the `--arch` flag with npm install or set the `npm_config_arch` environment variable:

+npm install --arch=ia32 electron-prebuilt

 ## About
