chore(deployment-serving_yo): #12 - Serving static HTMLs

* main concept: we do not process files produced by Grunt - the trick is to adjust Django urls to play nice with vanilla yo/dist version
* decided to serve AngularJS views as static html, not rendering them from Django templates - converting static htmls to Django templates would have involved too much fuss
* serving htmls as static content does not require changing AngularJS interpolation markup ({{ }}) in order to avoid clash with Django templates markup - problem arises when using Angular libraries with default interpolation markup in their templates
* circumvented inability to parse SASS with a site-level url work-around in skeletonDjango - hopefully this hideous trick won't be necessary if following will be answered: http://stackoverflow.com/q/20760123/1432478
* still requires some setup during real deployment of static files - example for Heroku: https://devcenter.heroku.com/articles/django-assets, but local version with DEBUG=True is fully functional
refactor(deployment-serving_yo): #12 - Serving static HTMLs  - got rid of crazy hack in Django URLs

Got an solving answer (http://stackoverflow.com/a/20773194/1432478) and used setting variables in a separate file (dev & prod versions)
