Fix broken parsing when hacker news has a solid color top bar for deaths etc.

The black bar across the top of Hacker News today for Aaron Swartz's death (and has appear a fair few times in the past for other deaths) breaks the app parsing. There may have also been a bar for Christmas (or it may have just been submission link colors).

Ideally the top bar in the app could also be changed to the top bar color on Hacker News when this happens although I don't know enough about ios dev to actually do this. Similarly this likely isn't done the best way but I just thought I'd muck around with it a bit and see what I come up with. Feel free to reimplement, just bringing up the issue.
