Fix "elem.parentNode is null" with Flashblock

[jdelStrother]

The Flashblock Firefox extension seems to take the questionable approach of removing video nodes immediately as they're inserted into the page, which causes an "elem.parentNode is null" error. What do you think to this fix?

hey @jdelStrother !
That looks great, could you change it to have smoe curly braces and break it up over a couple lines?

thanks!

[jdelStrother]

Sure, I'll do so tomorrow. (Though if that is the preferred style, shouldn't eslint specify "curly": "all" ? )

@jdelStrother good idea want to sneak in the eslint change in this PR and see if our linting still passes if not we can do a follow up PR.

[jdelStrother]

Done. Looks like the rest of the code is already using braces, so I've included the .eslintrc change in this PR. I can break it out if it proves contentious.

[patrickkettner]

ah man, perfect use of commits :]

[patrickkettner]

thanks so much!
