2016 conference brochure

[Allan Day <aday gnome org>]

Hi everyone,

This is a bit of an urgent task - we need to put a brochure together
for next year's conference, to send out to potential sponsors.

Jeff has kindly offered to print them out, and send them with the
annual reports. Printing will be black and white.

I've started a design [1]. It would be great to get feedback on this.
Also, we need text! Ideally a short summary of each conference, and a
description of sponsor benefits.

Allan
