(Bug5073) Basic foundation/SCSS set up

* Add a config.rb file, to use with compass to compile SCSS
* Add a .gitignore file, to ignore compiled CSS and SCSS cache
* Add Foundation base SCSS and JS; do not include vendor libraries
  we already have or won't use (jQuery; Modernizr)
* Note: have commented out the majority of Foundation modules, because
  we should focus on adding one at a time.  Starting with the basics
  for layout.
