Latest commit e6f8a8a Sep 20, 2016 @peff peff add 2016 survey banner
This adds a banner to most pages advertising the 2016 Git
User's Survey. The content is mostly stolen from @jnareb's
678f4a1, with a few minor
English fixups.

However, I think the banner CSS added by fc7ab3b
in late 2015 looks nicer than the old "promo" styles from
4818b27, so I've gone with
that.
