Split JS files into several different JS files.

index.html now uses ncc.min.js

debug.html is generated. it uses ncc.js

ncc.js pulls in the other different JS files into the project.

ncc.min.js generated with: cat js/* | ../UglifyJS/bin/uglifyjs > ncc.min.js
Added generation of git.html, which pulls ncc.min.js from github.
