Loan Summary Report; add option to include a separate Refinance column

There is a new option on the Loan Summary Report to include a separate Refinance column. Previously the "Advance" column included Advances and Refinances.

Note, to maintain backwards compatibility, if only the Advances column is included in the Report, it will continue to be the total of Advances and Refinances. If both columns are included the Advances column does not include Refinance transactions.
