Updated table with DRM, fixed contributor list, enabled my laziness, etc.

Removed the - in DRM-free in the json because it was easier than figuring out how to deal with it properly. Updated games.js, index.html, tables.html, json.html, and readme.md.
Added DRM columns to table view
Replaced DRM icons in table view with base64 images instead of sourcing an external image (correct or not, site may disappear)
combined css classes in table view in an attempt to make it shorter.
