As a press manager I want to run funding reports

[joemull]

As a press manager I want to generate reports that show funding for a given financial year, or a span of several years.

• I can view annual revenue by supporter across multiple financial years, in one big table.
• I can see invoicing status for each row, such as "No action needed yet this year"--word this better, "Needs invoicing", "Invoice sent", "Payment received", etc.
• I can export the data to Excel.
• Maybe I can also see and export visualizations of the data.
