Welsh Government Provider Dashboard round 2

A consortium level view of the Welsh Government Dashboard.  The Provider areas have now become consortiums with one lead provider and a varying number of sub-providers.  I've also added an average RAG status value for the consortium based on equal weighting of all the providers in the consortium.

Another addition I've added is the scrolling horizontal bar.  The previous dashboard was for a fixed 8 quarter period which fitted onto one sheet.  This time I've extended the time frame out to the end of 2014, so the scrolling bar allows you to move back and forth along the time frame. The 2014 date can be extended easily if required.
