Provide a home for live QUIPs

We have a family of documents called QUIPs, currently hosted on a heroku instance (which is likely worth keeping as a preview site for the works in progress, as it currently operates). It would make more sense for them (in their final, approved forms) to be part of our community web-site, with stable URLs that can be referenced from our Wikis and elsewhere.

Their maintenance is fairly straightforward (I could write a script to run as a nightly cron job, for example) as long as the site runs on a Unix-like (e.g. Linux) platform. We just need a corner of a suitable web-site to put them.
