Customer Based Reporting

This is *another* of those reporting feature requests, which should probably be lumped in with just 'overhaul the reporting please and let us run custom reports with all fields available', but seeing as this needs to be noted, I will make this request anyway.

There really needs to be some customer level reporting in the system.

Things like:

- New Customer since X days/weeks/months

- Customer Addresses

- Customer Contacts

- Customers with "x" Tag

I am aware that some of this can be exported from the Customer List but that is not good enough. We need sorting and filtering in a report to actually get the data we need.
