Lots of updates and example templates copied from Zurb site

I have done a bunch of work updating this templates, as well as the foundation-project-account that goes along with it.  
Some template tags needed to be changed to be compatible with [django-pipeline](http://django-pipeline.readthedocs.org/en/latest/), I wanted to use this because it also includes support for js and css compilers like sass and coffeescript.  I tired to get it to compile the scss for foundation, but it is very dependant on compass for the modular scale stuff, so I gave up on that for now.  But I will be using coffeescript in a project and would like to use django-pipeline instead of brunch or something similar.  Let me know your thoughts.

I updated the css classes for the icons to the new ones that are foundicon-*.  In order for them to all work I added the name of the icon set to the css selector.

```css
[class*="general foundicon-"]:before {
  font-family: "GeneralFoundicons";
  font-weight: normal;
  font-style: normal;
  text-decoration: inherit;
}
```

I also added a bunch of demos from the playground, these were a nice visual test to make sure things were working.

* [Responsive Tables](http://www.zurb.com/playground/responsive-tables)
* [Off canvas layouts](http://www.zurb.com/playground/off-canvas-layouts)
* [Icon Fonts 2](http://www.zurb.com/playground/foundation-icons)

I also added all of the templates from http://foundation.zurb.com/templates.php

I was planning on also using one of these templates to replace the current theme_base.html, a modified version of [So Boxy](http://foundation.zurb.com/page-templates/so-boxy.html) or a modified [Orbit Home](http://foundation.zurb.com/page-templates/homepage-1.html).

I think that the Orbit plugin needs to be updated still as well.
