Rewrites/privacy decentralized fixes

[Quix0r]

From last commit:

Rewrite:
- don't reference files - more worse JavaScript - from external CDNs
- this is a security nightmare when the remote CDN is compromised and starts
  distributing worms/trojan horses (see NSA scandal)
- this will give them away your user's IP addresses
- removed no longer used js/main.js as there is assets/js/main.js around
- moved css/js files in their own folder (assets/<css|js>)
- removed executable right from include/dba.php, no need for this
