Code cleanup to be w3c validated

[Outpox]

I'll need to rework the css for the keyboard (even maybe redo it) to respect correct css rules.
This issue is related to the html for the keyboard where I have :

<ul>
   <div> // div is not allowed as direct child of <ul>
      <li></li>
   </div>
</ul>

Fixed in the keyboard branch which should be released someday.
