- Some more screenshot updates @ https://github.com/cakephp/app/pull/150

Features:
- No frontend framework
- Semantic html5, responsive ( html5 check via https://gsnedders.html5.org/outliner/ )
- Plain modern look
- Optional LESS file supplied to get going with rapid development and adapting (the layout.ctp and webroot files will go into another PR against cakephp/app)
- No CSS class or div soup (see http://ruby.bvision.com/blog/please-stop-embedding-bootstrap-classes-in-your-html ) - rather based around complex css selectors
These variables are never modified why are they needed?
