Update attribute table

[gaearon]

Looks like we missed some updates. Chrome itself also did a few changes.
See separate commits:

• 16.3: f1b5f27 (just a table reorder?)
• 16.4: no changes.
• master: 31c1446 (this was a bug that existed since 15 and was fixed in Fix the "checked" attribute is not initially set on the input #13114)
• Finally, 1cfb490 is just a re-run of master with recent stable Chrome.

Going to merge since I need to rebase my PR on top.
I think this looks good.

31c1446 looked a bit suspicious to me, but it does seem like a valid bugfix. Checked (uppercase) changed but we warn about it. The defaultChecked change actually makes the property represent what user sees on the screen instead of always being false.
