Added a script for building distributions

Script can build full version and version without D3
Added watch commands

Files will be watched during tests and during beefy hosting
Changed builder from shell script to JavaScript

Allows us to take advantage of npm varaibles etc
Distribution files are no longer tracked by git

Run "npm run git-setup" to ignore tracked distribution files
Need a greater node.js version.
