Base for Receipt Management

This module prepares Odoo for managing receipts (sales and purchase receipts) alongside invoices.

On a partner (customer/supplier) form you get a new "Use Receipts" checkbox and a "Receipts" stat button showing the total amount of receipts invoiced for that partner and its child contacts. Clicking the button opens the list of that partner's sales receipts. When you tick "Use Receipts", Odoo automatically fills in the partner's fiscal position with the one flagged for receipts; unticking it clears that fiscal position if it was a receipts one.

Fiscal positions gain a "Receipts" checkbox, and the system can find the receipts fiscal position for a company (falling back to a shared one with no company).

In the Invoices Statistics report, two new filters appear: "Sales Receipts" and "Purchase Receipts". The existing Customer and Supplier filters now also include receipts, and the report's default filters keep the original behaviour.

On journal entries, the outstanding credits/debits widget is only shown when the entry is posted. The module also defines receipt document types (sales receipt and purchase receipt) so other features can recognise them.
