Started to make the site responsive

Started working on converting the site to a mobile first theme that is setup to
be optimally viewed on a mobile device, with media queries for increasing sizes
The bulk of the css restructuring for mobile display is now complete, just some
tweaks left to go
Modified the folder structure again to include images in the assets folder
Revised the theme to make use of the breadcrumb menu provided by Yoast WordPress
SEO - need to include a little reminder that this should be installed later
Added summary.php as a template part for viewing a summary of a post
Modified content.php for viewing the whole post
Made some changes to FSESU_Theme class to create actions for the various
included theme functions for ease of use within the template files
Removed some of the vendor specific css files in favour of linking to the live
files on the development sites
Removed minified css & js files in favour of using the WP Better Minify plugin
