Refacto more grunt

Alright 
I removed my angular hack to a more standard doc generation.
Now your grunt must content a more complex _view_ key with the demo and its dependencies into it : 

```Javascript
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    meta: {
      view : {
        humaName : "UI <repo>",
        repoName : "<the github repo name>",
        demoHTML : grunt.file.read("demo/demo.html"),
        demoJS   : grunt.file.read("demo/demo.js"),
        css : [
          '<any required css files>'
        ],
        js : [
          '<any required script files>'
        ]
      }
    },
    copy: {
      template : {
        options : {processContent : (function(content){
          return grunt.template.process(content);
        })},
        files: [
          {src: ['out/.tmpl/index.tmpl'], dest: 'out/index.html'}
        ]
      }
    }
``` 

I'm going to update angular-ui/ui-codemirror and angular-ui/ui-ace so you can see how to use it.
