Added angular-ui-router and moved content into templates.

Continuing the 'angularification' of the dashboard.  I added angular-ui-router and moved the content into templates within the main index.html.  I initially tried to use views in other folders but because everything runs locally (i.e. file://index.html) I was getting 'Cross-Origin Request Blocked'.  Ideally we're running on some server (node perhaps?) and these templates are loaded via ajax.

This is by no means complete.  Hoping to get feedback on a way forward.
