Include a "standard" link to the list of discussions

[mjang]

I've done some hard coding. (I couldn't figure out how to set this up "properly." But since this applies to all pages, I'm not sure if that matters.)

I don't claim to know any/all PR requirements -- I'm using this as a learning experience.

Ref #150 and nginx/unit#1299

Here's how it looks in the local build.

Somehow missed this in my review queue. Would love to replace the icon with either a GitHub logo or chat bubbles from Font Awesome and tweak the text to be more along the lines of "Discuss on GitHub" or similar.

I hear you, @callahad. However, finding where to add such icons is beyond my expertise, as I'm not familiar with how this is set up. My research suggests that this is loosely based on astropy/astropy#347.

I hard coded the link because my understanding is that we're planning to move this content to the new documentation tools that @danielledeleo and cohorts are working on. (If I'm mistaken, then I would also have to defer to their expertise on where to include something like the GH octocat icon in this repo.)

@callahad, would an emoji suffice? 💬
