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.
* Fixed the capitalization of gog and drmfree in the index.html filters
