removed substance-forms modifications from the dev branch. will place in a separate branch so that we can continue development

Added substance-rails gem and then included the appropriate js and css libraries into the asset pipeline

moved assets from app/assets to lib/assets. The files in lib/assets will be used by Rails unless override by an equivalent file in app/assets. Added logic to applicationController so that it will look first for a template in app/views/[:branded folder name] before using the default in app/views
