Updated bower dependancies, add foundation

We have decided to use foundation to be our CSS backbone.  A dep
on foundation was added to `bower.json` and `bower install` was
run to get the latest version of all necessary software.
Added foundation icon set.

Since the foundation icon set is not downloaded through bower, it
is placed in the css folder.
Added foundation styles to `index.html`

Most of the code was copied from
https://github.com/regdoug/ritplayers-web because it has a nice
RIT identity bar already implemented using foundation's grid
structure
