PHP Ajax handling class structure finalised
Live code editor improved on:
  - Now includes a file browser (still needs a lot of work but it's a start)
  - You can now switch between files (css, less, php, js & html) and make amends which will be saved automatically after 5 seconds or as soon as you press Ctrl+S - This will also re-render the live preview
Added jQuery Fancybox (a simple lightbox plugin) - Currently un used
Fixed bug in get_url_parts() where it was including query strings
Fix for deprecated jQuery function call $.curCSS
Fancybox CSS converted to LESS for consistency - Untested
Basic CSS changes to allow 3 panes (file browser, code editor & live preview)
JS side of ajax handler now preforms some of the basic operations it needs to, still a work in progress and as it's required it will be enhanced
