Contributions and corrections

Add contributors, then pledges. A pledge is not cash. Enter partial receipts and verify them before allocation. Use a different finance member where independent approval is required. Allocate verified receipts only to that contributor's pledges in the same event and currency. Overpayments remain unallocated credit. Reverse a mistaken receipt with a reason; its original record remains. Add the replacement separately. Reports show verified net collections, outstanding pledges and unallocated balances.
