Initial test data for the non-profit-audit-reports contrib application.

The basic idea here is that given non-profit-test-data.ledger herein,
there should be a script that I could run, in this fashion:

    $ general-ledger-report -b 2011/03/01 -e 2012/03/01  -f tests/non-profit-test-data.ledger

that would generate:

   non-profit-test-data_chart-of-accounts.txt
   non-profit-test-data_general-ledger.ods

Note that the ODS file currently has placeholders, as I haven't fully
figured out how to use the =hyperlink() function to make relative
hyperlinks.
