Included bootstrap-glyphicons.css instead of removing the css call in base.html

base.html was referring to bootstrap-glyphicons.css, which was missing in css folder. 
Latest distribution from http://getbootstrap.com/ doesn't have this included, adding it from - http://glyphicons.getbootstrap.com/css/bootstrap-glyphicons.css.
