Merge for #101 CORE API integration 

This is for #101 but includes a couple minor fixes.

* Dates injected by JS into the DOM are now written in as ISO formatted dates.  This makes life easier.
* Date parsing has been converted to use python-dateutil
* The merge included switching form Django templates to Jade templates
* Django Form usage was introduced after @jezcope original pull request was submitted, so thats been merged in
* Stop with the environment variables!  A settings_local file has been introduced to store API keys like CORE_API_KEY
