Allow project logo & colors

[bcipolli]

Each project has it's own logo and look/feel. It'd be great to give a bit of that in the preview and project pages:

Perhaps defining a "logo" field in projects.yml, as well as a primary/secondary color that could be used to style the project preview and full page?

Now you're getting picky!

Just kidding, that's a great idea, and relatively easy to do. +1 from me as well!
