Broken with Atom's new shadow DOM

[danielmahon]

Git merge "changes" do not appear when the Shadow DOM is enabled in Atom.io settings. Only the headings "//our changes, //their changes" are visible.

Hmm, I think I tried it out earlier when the shadow DOM was first introduced and noticed similar breakage. I didn't investigate further then because I believe an API or two that I wanted to use were still in development. I'll have a look the next time I spend a day on this, thanks 👾

Er, this is now rather more urgent. Fortunately I believe #93 might address this, but I'll need to test. I should have time in a day or so.

[smashwilson]

Well well. #93 ended up being more work than I was hoping it would be. Let's see if I can fix just the shadow DOM bits, instead, to unbreak things quickly.

Back in business!

Still a few visual issues, but we're up and running again. The next release should be operable again.

thanks!
