In case anyone wants a theme that is just an extension install, I've got those for you. Link are below.

Pic of it in action.

Chrome - https://chrome.google.com/webstore/detail/slent-dark-theme/dngioombhpmopiaciaehejodpeangeif

Safari - Done, but waiting approval from the Apple overlords. -.-
Safari Beta - https://s3-us-west-2.amazonaws.com/safariextension/Slaent+Dark+Theme.safariextzBeta for Safari is available while the extension is in review. This is the same as the submitted one, but you'll need to install it manually.
To do this just download the file from the link and double click it. Safari should recognize it and allow you to install.

Firefox - https://addons.mozilla.org/en-US/firefox/addon/slaent-dark-theme/

Leave a post here when you find issues and I'll update them.
