Tweak stylish newsfeed -- aligning event-type badges for easier scanning

Fixes #219. I hope display: 'inline-block' is well-behaved on all browsers, I've heard it might not be

So we should test this on IE. (I don't know how to use BrowserStack right now, but it would be cool to learn!)

@erose nice, awesome improvement! 👍

There's no problem with using display: inline-block in IE, but it's great to think of this and check layout-type changes on IE! I can help check this tomorrow, but if you want to give browserstack a spin, just visit https://www.browserstack.com/, sign up and then click on IE11 on the latest version of Windows. Then you can visit the demo site in IE within the browser, and sign in with the demo account.

I think at the moment only @alexsoble and I can deploy branches to the demo site without merging to master, but we could talk through that and change it tomorrow too. Or since we're pretty confidence this change will be good, you could merge optimistically then verify on browserstack.

Okay, cool, looks pretty easy. I'll merge optimistically and check.
