add .idea to .gitignore due to PhpStorm
Updated to now be Foundation 5.2.2 (this should get rid of that Orbit bug)
Updated source URL for the style guide to now pull from github using http instead of ssh, this is due to git caching the #master when using ssh and when doing a bower update it will grab the cache instead of the latest #master
Added /app/inc/ directory to /_resources/inc/
Styleguide header and footer updated to point to the _resources style guide versions instead of _assets
