Over the past couple days Roan Kattouw and I have been pushing out changes to enable protocol-relative URL support. We've gotten to a point where we think it is stable and working.

We've enabled this on test.wikipedia.org, and plan on running it for two weeks before enabling it elsewhere. Please test if everything is working properly, especially with regards to the API and bots. Report bugs in bugzilla if any are found.
