fixed various logo names because they were not very descriptive, and moved logos for companies who've not been able to renew their sponsorships to another folder, so they don't get unintentionally included in stuff they shouldn't.
Also added a redirect for the very unhelpful /contribute/ page to point to the wiki until we can get that page in better shape.
