Creative Co-op have recently prepared some brand guidelines for
CoTech, including a new logo, typography suggestions and background
images. This commit restyles the site to apply, as best we can, these
guidelines. It's hard to split this into smaller commits because the
decision to use a black background colour means many things have to
change.
Notably we've removed the "about/join" footer, as it was hard to
choose a bg colour and without one it became more apparent that this
footer was more in the way than useful.
