build process without ruby, just node and npm

This is pull request for #34

Use DocPad for build process.
For each conversion type (coffee -> js) you need a docpad plugin (npm module) and define it via the extension, for instance: **script.js.coffee**
usually the plugins don't need any configuration, they just recognize the files by the extension.

the deploy stuff (scp and ssh) is a shell script now: **deploy.sh**

The .html files could also be moved to **src/files** (which is used for static files) but I plan to do a next pull request and use a template engine like Jade to keep the html code DRY ;)

That's the reason why the html files are located at **src/lib**
