Deploy an official NuGet package

Created by: supergibbs

I know this has been brought up many times but Bootstrap can currently be installed via a GitHub download/clone, CDN, Bower, npm, Composer and Meteor. Adding NuGet would be a helpful addition.

The best NuGet Bootstrap Package is managed by Outercurve Foundation. Unfortunately their package has had issues in the past and is often out of date (still on v3.3.4 currently).

@mdo suggested I open an issue to see how much interest there is. If this is something the core team would consider, I believe it could be fully automated with the addition of a couple files. I'd be happy to take on setting it up.
